Perhaps I'd like to design cars but I don't think I'd be much good at it.
There's no learning without trying lots of ideas and failing lots of times.

However I wasn't very good at the sciences or didn't have a lot of help in the sciences or something but certainly didn't set science for my A level. And when I came to take my A levels I didn't get a good enough result to go to University.
