I wasted about 9 years and about 150k on drugs when I was young (16-25). I'm glad that shit is out of my system.. I don't regret it because I have seen guys that were clean through their 20's and turn in to addicts by their mid 20's and not stop. Kinda ass backwards if you ask me.. Get it done and over with! Bang as many chicks as you can, enjoy your teens and early 20's than chill the hell out and enjoy the woman you decided to stay with and not the first piece of ass that got you whipped! Yes these are the keys to success! (Money, Sex, Drugs) By 25 STOP! You've sampled all the water parks and got your Dip stick wet enough times to know if she's the write one by then! Don't EVER stop working, it will be the only thing keeping you sane and your not getting any trim without paper!
