Seems like you know what's up.  Self control is the key.  What I've learned from my own trips along with other trips is that you learn more about yourself more than anything else.  "Yourself" being an individual or as a "whole". 
Haha, and about weed not giving you any answers, only questions.  True.  But that's the point.  There's no fun in figuring something out if you don't try for yourself.  In my opinion, weed and mushrooms are a coincidental gift from this glorious planet that will only help us further our evolution as a species more mentaly than physically.  And also give us a better sense of respect for our surroundings.  Because honestly, the majority of us are very cocky and ignorant due to the fact that we are the species that is at the highest point on the ladder, but the ladder is alot fucking taller than we can imagine.
