I just left my job of 12 years with the worlds largest Telecommunications company. I can honestly say that every day in a cubicle was the worst day of my life (yes that is messed up
. I got so tired of constantly looking to the sky and wishing that I was flying that I finally decided to make my move.
After minimizing my lifestyle and paying off debt I completed my CFI and walked away from my desk job. I have never been happier. I now make 25% of my old salary but I am happy and that makes everything worthwhile. I am having a blast instructing.
As everyone has already said, support from family is key. None of this would be possible without the support of my wife.
Good luck to you
