I'm not really in it for the money at all. I DO however want to someday reach a level in my career where I am making a good bit of cash to enjoy some of the great things live has to offer. I'd like to own a plane someday, and a boat. Basically two things to throw my money away into.
I'd also like a comfortable house in the Chicago suburbs, and the ability to NOT worry about bills.
But to do all those things I really can't rely on JUST flying. That's why I'm getting involved in other things. I'm trying to get part-time employment with two different aviation companies (non-flying positions), and also want to start writing for aviation magazines for some extra income. We diversify our portfolios, why not diversify the income that those portfolios are fed from?
I think you shouldn't just limit yourself to flying. Find other things you love, and do those on the side. That way if there is a downturn, like there is now, you still have something to sustain you. Something other than being a waiter at TGIFridays or pumping gas with William Robert down the street.
