As I ponder the question what pops up in my head is that it's important to make sure that I do know where I want to go in life and then to make sure I do what would lead me there, and not do what would keep me from there. Make sense? I mean if I want a good life then I ought to limit the bad stuff, right?! I mean, that would only make sense.
Another thought is to *seek the wisdom of those who are where you want to be, or are well on their way to getting there on some level. Evaluate your life, your choices, your friends, your spending habits, etc. Make whatever changes necessary to help you get on your way to wherever it is you want to go.
*This can be done through reading books, and even actually setting up appointments with people. Make sure to have your questions written down before you meet them, and take good notes.
And finally, get moving!
