I feel the need to quote Bill Hicks again:
Aaah, they lie about marijuana. Tell you pot-smoking makes you unmotivated. Liiie. When you're high, you can do everything you normally do, just as well, you just realise, it's not worth the fucking effort. There is a difference. "(toke, toke, toke) Sure I can get up at dawn (toke, toke), go to a job I hate, that does not inspire me creatively whatsoever, for the rest of my fucking life. (toke, toke) Or I can wake up at noon and learn how to play the sitar!"
