Don't find your talents, cultivate your skills. You likely will never just "find 1 thing you are really good at", but if you find something that's worth getting good at and stick with it even though you suck, eventually you will become good at it.
It's important to focus on WHERE you want to cultivate your skills.
You're probably not naturally good at anything in any meaningful sense.
You're going to have to work hard to be good (in a meaningful sense) at anything worth being good at.
So what things do you enjoy cultivating your skills?
If you don't enjoy practicing guitar - you're never going to be a guitar virtuoso - because you're never going to want to pick up your guitar and practice.
That's my approach, anyway!
