I had an IT career for 15 years. I finally had my dream job, Director of IT for a medium sized but very well known auto club. Then the merger came. The larger club took over and I became a Systems Admin II. The new bosses were.. well lets say less than stellar. I quit on a Monday after a 3 months in hell project that I did not nor would not complete.
I joined a friend who had his own construction/remodel business. It has been good but the money certainly is not near what I was making. I've had to make some lifestyle changes but it has been worth it. Try to make sure you have some savings to fall back on for big expenses (like a new roof).
I'm even thinking of returning to IT now as my head has cleared from the depression of the last job. Or maybe return to school for a Master's of an IT forensics job.
Good Luck, You'll probably do fine.
