When I was young, I wanted to be a doctor.
When I graduated high school, I wanted to be a doctor.
When I started college, I wanted to be a doctor.

When I realized I liked taking shit apart all my life, I decided to become an engineer.
When I saw how unusual electrical engineering was, I decided to do that.

Now I get paid to take (electrical) shit apart. But then I have to put it back together.
Note: I took apart an electric can opener when I was about 15. Bad idea

You're only 22. Start on a path. After a while, if you don't like the path, then change it.
