So, lookin at my current state, I'm single, been emotionally scarred by two crazy girls who claim to know what love is, a 15 year old, long haired, acne stricken dude going into his sophomore year of high school. I look around and see that most of my friends have yet to think about their futures or their plans for life, we laugh and joke but I know that they're screwed once they graduate. And most people my age say they don't know what they want to do with their future. But I have too many choices, I'm a very talented artist and have made money in commissions for old friends and neighbours, I'm writing a book and have edited one my friend went on to self-publish, I know how cars work and could be a mechanic, I've played Clarinet and Sax for 6-7 years now and want to learn guitar... I just want to do too much. I want to skateboard too. Too much at once, and I could do all of these and see myself going to Art or Music school for multiple things. I drop interest and pick up new ones at the drop of a hat, and find interests in girls just to get turned down, but I stay persistent, lol. I'm very intelligent and a good comedian.... Anyone have advice on how to pick or sort my priorities?

One, how about, being a free lancer?
Although that can be tough (Money, Time, Location, People,) but you can get to try everything you want.
And it also seems you have a talent to be a jack of all trades.

Two, pick one choice and stick to it for your life

Three have a main job and multiplie side jobs

Four go travel then decide.
It is always said, you gotta have an adventure, before you truly know what you want to do.

Freelancing, eh? Possibility. Travel, the monetary needs are too great, having multiple jobs? Not my thing. Picking one choice seems impossible at this point. Eh, I mean freelance work means I'm my own boss. Though, travel would help. "What is adventure unless we risk our days for what we love?"

There's always something you really want among those choices.
Like Leonardo Da Vinci, he want to learn everything that came to his mind, but in the end, he stucked on what he really wanted from all of it. An artist.
Maybe you're just thrilled at it at first, like if you saw something exciting, you'll want it, but in the end, you can't stick with it like it's your life.
Choose the choice that will complete your life, the one you really want.
Sure decision-making is hard, but think of it hardly, think about the benefits you want to have making that choice, and do it with no regrets.
Also, better hurry. Your time may be late.
But think of it carefully. I mean..CAREFULLY.
So there~
BTW, are you the chrome I know? -_-

Hey. Sorry, if I got back late, but Da Vinci DID get to... Almost every form of the Arts. And no, I don't think we have met before. I go by Chrome, mah name's Kyle.
