I think it depends possibly on what stage of your career you are at. I admit, I do eat, sleep and breathe flying and studying...and having to fit it in around work is tougher than full time study at University! I'm always hiding in a quiet corner in our library at lunchtime and my colleagues know that i'm not to be disturbed.
I know that feeling well. At age 41 I'm having a year where, right now I'm not studying for any new qualifications. This is, I think, the first time that has been the case since I was 13. It also won't last I'm quite sure!
