First you must get out paper and a pencil. Write down all the hobbies/experiences you liked doing as a child up until now. Make sure it is written from least recent to most recent.
Second step is to narrow the list down to three things. If you haven't done a certain hobby in awhile, cross it off. If you noticed you always liked doing a couple activities, keep them on the list.
Next, research those hobbies and find certain jobs that require those skills. Balancing wages also helps you figure out how much money you want to make.
Finally, attend multiple classes in high school, college or community. Learn to work with people in the same area. Once you know where you are most comfortable or outgoing, decide and live your life!
