The concept is about being a net positive influence on her life, in addition to a monetary or material deliverable goal.
In general, the SD has significantly more life experience, I'll even say successful life experience, than the SB. There's a reason she's in the sugar life, and it's rarely just for the fantasy old-guy sex. If you develop a real friendship/attraction/companionship (or more), and both are at least somewhat invested in the well-being of the other, then it's often a matter of helping the SB develop better life skills that will help her be more successful in her goals.
Examples: Help her learn to save and budget her money. Help her with time-management skills (so she won't get fired again for being late to work). Help her understand how the impact of local, state, federal, and international events will eventually affect her life. Teach her how to prepare a resume and improve her interview skills. Maybe even expose her to social causes that you (and she) believe are important.
The point is to help her develop as an adult and have a better chance at a long, prosperous life... Like you would do for anyone in your circle that you care about. It starts with your assessment of her needs, based on observation or her direct input. That assessment will happen naturally over time as you meet and enjoy your arrangement.
I'll close with one caveat: she has to want this kind of help, beyond the cash. Some SB's are just in it for the money. There's nothing wrong with that. It's just how they want to play. In my experience, those arrangements don't last very long. As soon as she finds one or more SD's with bigger wallets, she's likely to ghost you and follow the money. So you will probably never get to the "leave her better" phase with these.

And Herb's comments are, as usual, right on point. I will only add that being a great male role model is extremely important. Many of these young women only have experience with guys who are jerks with zero relationship skills, no communication skills, etc. They can't help but treat the girls poorly, and in response, it's understandable if they in return think men are all assholes.
We get to show them a better way. Always treat them with respect and affection, always try to meet their needs as well as our own, both in the bedroom and elsewhere, never demean them, never be aggressive or violent. It may really open their eyes. At the least, they will have much higher standards when vetting future partners.
