It means you can make the future whatever you want it to be. Feel Lucky

It just means...

...you've already attained the pinnacle (or surpassed it) in your life.  It's all downhill from here...

Don't worry...i've gotten some shitty fortunes outta cookies but its had almost no impact on my life.

... because in heaven there is no beer; that's why we drink it here. Via con huevos, amigo! (I love Paul Newman).
