Well, if you started off with an age, it would help, as X+3 could equal a lot of numbers! It also depends on what you want to do...if you are happy bombing around in the lower levels of the industry, the getting started at 30 or 40 isn't really out of the question. If you want to get to the left seat of a 777, then get on it right now (although a degree is a very useful thing to help you get there..)
