I have a friend in his 50's who's smoked weed all his adult life. He told me that the thing he regrets most about it is that is sapped all his ambition.
I have a friend in his 30's doing the same. I see him and there's no ambition.

Lest you think I'm preaching at you, I'm not. I don't care if you flush your life down the toilet. But I do think you should be aware that that is what you are doing when you make that choice.
