Well you've pretty well described my life ! Part-time lecturing provides a guaranteed income, pays the mortgage, keeps my brain active when the weather is ****. Flight instruction keeps me in the air (weather permitting) and I just love it. I would suggest that this may be the perfect formula. Alternatively, if you want to get rich or famous you could do something else. I'm happy though - hope you will be too - 1nstructor.
PS My life is not recommended for sensible people or those with debts, children, high mortgages, second homes or an interest in fine wines or expensive cars,
