yeh, look for delayed gratification and avoid all the instantaneous gratification you receive from things like tv, computer games or looking at porn (i've taking wanking off my list of things, cuz i read it boosts your testosterone in the morning)
try not to think that mere thinking will solve your problems or get you motivated no matter how much thinking you do put into it. sometimes it will, but it usually won't produce the great results you want.
what you need to do is feel emotions to drive you. they have their negative effects (uncontrollable rage or burning jealousy) but just as strongly have their positive ones.
many people try to motivate others by saying "if you really desire something, you will get it". that's all very well saying that, but how do you truly desire something? just by thinking about it and all the things you could have from it? no, you need to feel strong emotions: strong desire to have something or potent anger for not having something.
for example. someone has a craving for cigarettes. their desire to have them and anger from being without them are very strong and so they will naturally take the necessary action to get cigarettes no matter what, even if it is offering a bj for one (i didn't accept it, honest)
so to get your emotions in action, imagine where you want to be or what you want to have. feel the same feelings that you would have. take a good 10-15 minutes every day doing this. try playing some motivational music while doing this. i'd personally recommend trance or some heavy metal (andrew wk), but i'm sure you've got your own
the reason smokers have the burning passion for more cigarettes is essentially chemical, but that in turn sparks a powerful emotional drive; the same kind of drive you must feel through your imagination.
warning: don't go out and get addicted to cigarettes just so you know what i'm talking about
