I run a business. I stepped out of it a few years back for a job with a bit of promise - it was a good move for me. However, pressures from running a business (it didn't stop when I left, my wife ran it) led me to leave the job. That was a bad move. Now thinking of a career change again. For me, the change was good; jumping back into the fire of running a business was probably not the wisest choice for me. Hope that is helpful.
