I don't know what you're selling but if it's a big purchase/commitment for them, you want to know that they're qualified, and when they're looking to make a decision.  After a couple of closes, you'll get a sense of who your serious prospects are and who to spend your time and effort on (and who not to.)  Be excited about what youre selling!  Create urgency!  Find them exactly what will fit their needs rather than overwhelming them with options.

Cars - there is difference between selling Chevy, Camry, Chrysler versus selling Mercedes, Audi, BMW, versus Bentley, McLaren, etc.

Same with hand bags high end versus every day ones

Kitchen tiles- depends in store in designer store, Home Depot, lowes or door-to-door

If it is pyramid scheme you are screwed
 

Being a commissioned sales person is just like being in business or being a hooker for that matter.  

It is up to you just how successful you will be. One of the biggest things that will help you is to be honest with yourself, and be your own harshest critic in your quest to be the best. Unsuccessful salespeople, hookers, businesspeople et al will blame others for their failures. The surest sign of a loser is to blame "the stupid customer". In sales there will almost always be a key point in the presentation, negotiation, meeting where the sale will hang in the balance. You do one thing right and you get the sale, you do one thing wrong and you lose the sale. ALL of us are going to fuck up the occasional deal by saying the wrong thing at the wrong time. The key is to be honest with yourself and to figure out where YOU went wrong so you can do better in the future.

Lastly, find a product/service that you actually like to sell. If you aren't a car person, don't try to be a car person. While there can be a certain amount of acting as a salesperson, just like there is in being a hooker, the more you can just be "you" the more success you are going to have.

Thinking back on my life, since my military service getting close to 40 years ago, I have not drawn a salary or been paid by the hour for more than maybe a year combined in my total adult life. I wouldn't know how to act if someone were to be me a paycheck not tied to productivity.

Selling takes time to master. I'm in industry with a lot of competitors that sell the same type of product that will fill the customers needs just as well as mine. That being said I have about a 90% closing rate. One thing to remember anyone can sell them widget x and maybe even cheaper than you can but, you are selling yourself as well. Maybe not the best choice of words for this site lol!! But seriously if you come across as genuine and personable your chances of closing the deal rise greatly. I don't know how many times I've spent an hour in a customers home and probally 45 minutes talking about everything but what we are selling after I've looked at the situation and what will suit thier needs. I find a common ground, kids sports, or the guy has a nice fish or deer mount on the wall. I just talk to them like someone I met at a bar and just shooting the breeze. On the way out I'll hand them a proposal and tell them to call if any questions. 9 times out of 10 when the homeowner and their significant other are setting down to make a decision they will think "that Case guy sure was nice lets buy from him"
That works if the customer isn't in dire need of my product. If they are then it's s more focused on what they need approach, still honest and friendly but not near as much idle chit chat. When this situation arises knowing your product inside and out as well as your competitors will usually close the deal on the spot. Know your competitors product not to talk trash about it, that comes off negative and kills any trust you've built with them. But know the advertised features of their product and how yours is better. Knowledge is power when closing a deal.  
Learn to read people some folks only care that it works some want to know how, learn the difference and be ready to present both pitches to whomever your dealing with that day.  

And don't judge a book by the cover I've had folks in 500k houses ask about financing or just say they can't afford it and guys in house trailers that look broke count out 5k plus in crisp 100 dollar bills from a coffee can.

Last and most important only promise what you can deliver. I've actually closed deals where a competitor promised something to be done in a timeframe that I know is impossible. When asked to match that I tell them the truth I honestly can't and offer reasons why with a simple I don't know how they can do that, since our services are so similar snd we are likely buying from the same supplier. Makes them second guess the other guys credibility.  

Ok enough of my soap box, good luck in your new venture!!

No matter the job, if you chase the money, you will never have it.

If you focus on the customer's needs and how to meet those needs and what you have to offer them ... then the money will chase you

To excel you have to be constantly prospecting. Either be at the office constantly cold calling or be outside constantly meeting potential clients through various types of ways. You can either go to them or position yourself so they find you. Your key to success in sales is to somehow establish recurring business and referrals. To do this you need to network, you need to be likable, you need to be able to quickly establish rapport, use every advantage you can.

Sales is a means to an end. The end goal is to always to have equity. Salesmen don't get rich off their commission, they get rich off their investments. Purchase rental property and rent them out, speculate condos, open restaurants, purchase stock, real wealth is not in dollars its in equity. Sales is not a steady income job so you need to get some equity in either the place you're working at or some other investment.  

The product does not matter. And reading advice off a forum wont help either. You have to go out their and try to sell, then learn and adapt. Common sense.

No matter how "honest" theymake themselves look, the more of a scam it is.

Tangible sales with immediate results is way easier than intangible sales. If you're selling a "widget" its easier to sell. If you're selling a concept, not so much. Here I would say you're selling something tangible. Its easier to sell pussy at a high price than something intangible at a very low price.

But if you're really good, competitive, and ready for rejection, try it. If not, well, might want to keep this on the side until you get a good client base and steady base income in the sales job.

It's hard.

I was a commission only salesman for about 8 years.  I sold the best hand tools on the market.  In my experience and opinion, what you are selling definitely matters.  Before I was introduced to sales, any time I would hear a reference to a salesman, I would think of a used car salesman.  You know, dishonest, untrustworthy, pushing product on you that you really do not want.  
I bought a tool franchise in 2006 and became a commission only salesman.  I loved it.  I never felt like I was "taking" people.  I never pressured anybody to buy anything.  I developed relationships with customers because they were helping me put food on the table for my daughter.  I sold them product that directly impacted their ability to make money.  I always felt like I was helping them and providing a service.  Generally speaking, the franchise managers would tell us not to get close with customers etc because they are not our friends etc.  I learned that was bad advice.  At least in my industry.  I treated my clients how I would want to be treated.  If they wanted a product from me that I knew was poor quality or whatever, I would tell them not to buy it.  You cannot ignore a salesman that tells you not to buy their product.  

A majority of the product I sold had a "lifetime warranty".  Many franchisees hated this part of the business.  They would feel like they were spending time repairing/replacing product for free and not making any money.  That was my attitude at first because, that is what I was taught.  At some point I realized it was the wrong attitude.  I began to use every opportunity to educate, inform and sell to my customer.  A free service is only free if you do not capitalize on the opportunity it presents you.  At the very least, I could repair a ratchet and hand it back to my client with a smile.  If nothing else, it was an opportunity to help the customer realize that I am diligent and happy to uphold the service that is included in the premium price he paid for his ratchet.  Better case scenario, I plant a seed about a tool box color coming out or some hot new tool to help the mechanic get a tough job done easier/faster.  Best case scenario, while customer is standing around waiting for repair, they notice something they need or want and buy it
