'I will never give it up, not even when I am an airline pilot'
Well I didn't, I don't think I could have afforded to stay in instructing for a living, but instructing as an extra is STILL enjoyable - the only thing I would say here is, don't undercut the rates. I don't NEED the cash ( though it helps pay the bar bill), but it is not fair on those who NEED to instruct if you do it for nothing, or less than the going rate.
