The Idea Process

I was talking to Elber not to long ago about what I really wanted to do for my senior project and he said anything as long as I had fun. That just made me more confused. He said that a good idea was to shadow a doctor. And I have asked my doctor and my dad's doctor if I could do that and they said they wouldn't mind at all. So now I'm split in between the two: coaching a little league baseball team or shadowing a doctor, which is what I want to be. Elber also mentioned that doing the latter would look better on my resume and colleges will think it's great. So when deciding should I choose fun or future? I'm more confused now than before I ever started thinking about the project.
