I’m 35 and I have been in your shoes. It took me two years of floundering about in college before I found what I wanted to do. I’ve always gravitated back to jobs where my natural abilities are utilized. Not everyone can do every job and do it well. Everyone has a talent or ability of some sort, find yours. I would caution you to be careful about making a career of your hobbies or outside interests. I have found that my hobbies serve me far better as relief from my career and I enjoy and look forward to my hobbies more than if I were exposed to them constantly.
Start by looking into some very broad categories. Like medicine, technology, construction, the arts, etc. Wipe the slate clean and don’t immediately discount any paths. Then find a way to get exposed to these categories. I did this through volunteering which was very rewarding in and of itself. For me I love medicine. I love everything about doctors, hospitals, patient contact, etc. So in high school I got involved in volunteer work and got to do some amazing things. Ultimately I was not able to become a doctor. I didn’t have the core necessary to become a great doctor. You will find there are a ton of volunteer possibilities for many many career fields.
It really is up to you, there are no tests you can take or advice anyone can give you about what makes you happy.
