To really make it as a career CFI and/or DPE you need a lot of energy. You're busting ass all the time.

I'm lazy, I like 15 days off a month and not having to hustle every single buck I make.

If you enjoy instructing and have a manic personality, then it might be for you. Maybe you can do some corporate/135 on the side.

But remember the liaibility...it takes a LONG time at $50K/year to pay off a $5,000,000 lawsuit.
