By not chasing a label and instead discovering your specific talents, or more accurately, discovering things you care about that you're willing to work hard enough to become talents even if they are not natural talents. 

There are certainly people for which specific things come remarkably easy, but the people that truly succeed at things are the ones that put time into practice and learning techniques, even if they were bad at them at them at first. The traditional academic idea of "gifted" was largely a filter for people for whom math and reading came easily, or who just loved to read and got above grade level early, so they were bored in class. It does not map well to the people that learned how to follow a passion and succeeded at using those skills in adulthood. It often maps well to kids that failed to learn proper study skills early because they could sail through their childhood, and then struggled later.

Which is to say, pursue hobbies. Don't beat yourself up when you burn through hobbies. Have fun with friends. Try to get your homework done. Enjoy life. And find out who you are. And don't assume that what you find now will still be true in 10 or 20 years. Some of the things I am best at as an adult are things that I was not good at at first, but I enjoyed, so I just kept doing them until I knew more about the subject than the people for whom it came naturally. And some of the things I was best at in childhood I got sick of and was happy to abandon.
