E.g. in no particular order: metal smith (silver gold etc), welder, carpentry, plumber, mechanic, fine artist, sculptor, textile. Basically the 'real trades' that have been around and should be around for many years.
The type of jobs that the white collars can't do without.
Either you outperform other CEOs and get rich on your own business, or you go this other path as I exemplified :D.
Now the gray zone is your regular 9-5, probably good co-workers, you make good living and work to live. The downside is that flexibility. So you need to think about what trades are you willing to make. I didn't mean to sound so 'dramatic' and pretend it's all black and white.
