What do you enjoy doing that you know you will perform well at if you choose to make a career out of it?

I'm a college student studying Interior Design. When I was a senior in high school, I took an Interior Design class that lasted for one semester and found that I loved it, even though I knew that it was only an introduction to what I'll actually be doing. I maintained an A the entire semester, and only missed 5 points on the final project (I forgot to include a material sample for one of the rooms in my house...) It took me a while to realize what I really wanted to do with my life but once I chose a path, I didn't regret it one bit. 

I hope things work out :) Good luck!
