Do you have kids?
If not, the best idea is to change companies within the same industry. As long as you don't burn any bridges on your path, you can end up back at the same company in the same position making 30% or more than you are now.
I've known a lot of guys who have done this. Unfortunately, I knocked my wife up three times so I can't endeavor on the same experiment. I also carry around a great level of envy and hatred towards my friends who have been successful using my advice.
