it all depends on how you go about things. try to schedule times where you take a break to get high. today was a successful day for me. i smoked early in the morning and i've been cleaning my house since 8 o'clock this morning. just keep yourself occupied, you wont even have to think about smoking marijuana and if you do, just remember how you get when your stoned and apply that to your desire to be productive during the day. it's all in your head, man.
