Time management

I've been having trouble managing my time as of late. I had to make a few difficult choices over the past month or so in order to live my time as best as I could, but I don't know if I like leaving things out.
I think the problem lies in my boredom. No matter how much I may love something, I tend to get bored of it quickly and move on to something else. It would explain why I am a Jack of all trades, but master of none -Sorry for the cliché reference-. One week ill dedicate mostly to playing a video game, the next week ill play guitar or maybe get drunk every second night. I never stick to one thing.
I see people getting good at one thing, and I can define them as such. "The-guy-who-kicks-ass-at-drums" or "The-chick-who-will-revolutionize-thought" and so on. I can define everyone else but me! Maybe its because i'm seeing everything in the first person, and it takes an outside influence to determine what kind of person I am. We are our own worst critic -Sorry again-.

Who knows.
Maybe ill find something for me. Maybe i'm happy the way I am now. Maybe ill always be "the-guy-who-is-always-doing-something-different-and-keeping-his-life-fresh-and-new".
Whatever keeps me sane I guess.
