First of all, everyone has talents. We usually even have talents we never discover, simply because we don't try every activity in the world. I guarantee you have a natural talent for at least one thing, and you have the capacity to become very good at many things.
Depending on how old you are, your options for exploring new activities differ. If you are still in school, you could "try out" a bunch of new things pretty quickly by talking to people who belong to various clubs, and possibly attending some meetings. You also may want to try some of the things your friends are good at. They might enjoy teaching you, and who knows, you could discover that you enjoy the same activities.
Sites like this are also a good place to test out new interests and hobbies, because you can easily find people who are willing to talk you through how to get started, and then you have a built-in support group of like-minded people.
