Bitch, let me tell you an actual fact. The human mind works in absolutes, there is no concept of "maybe," There is or there is not. There is no "maybe," there is no "later," there is only now or never. There are actual studies on this shit. You have to work with your mind, don't fight it. Don't try and tell yourself "maybe later." Find something you absolutely know you want to do and then do it. Immediately.
Find that seedling, find what you consider interesting, or something you might want to pursue. Then pursue it. Like anyone else who got into programming, I wanted to make games. But I got really hooked on program design, and now I've got my own little zen garden of software I've written. Business software, not even games. Just shit I made to make myself feel good about myself, that I studied and worked hard and designed these wonderful systems. I didn't "think on it" when I started that, I just picked up Game Maker and started teaching myself how to program. Everything else followed naturally. That's all you need; find a way to express yourself that comes naturally. It can be literally anything. There's this episode of King of the Hill, "Movin' On Up", where Luanne starts to go crazy from her roommates being assholes. Hank comes to her and says that he deals with the same stress from his own friends, but he stays sane because he has his lawn to tend to. He says to Luanne "You need to find your own lawn" which are words that stuck with me. Luanne then found that she enjoys tending to her pool. That's a zen garden, you need to find a zen garden. Whether it's programming, or lawn care, or pool maintenance, or fishing, or whatever the fuck it is. As long as it's something you know for a fact you're going to care about. Something you can turn into your baby. But you have to do it right now. There is no later.
