I was talking to a friend of mine the other day. He is self employed and many years ago, I taught him to fly which is how we met. As he has his own business, he has never gone down the path to an aviation career, but his PPL has given him an interest and success in air racing and he has owned several A/C. We were discussing another friend of ours who decided in his 30's to give up a very successful and lucrative career as an architect to make a huge financial sacrifice and go flying for a living. He did well and now, a number of years later, is in the left hand seat for Airtours. He tells us he is now totally sick of the job!! At least if he does give up he can go back to drawing houses for a living.
