@tindall As IT guy (after my useless dev diploma), the only limitation I had was "it's better to do nothing than to do harm".
Makes 99% of jobs out there unsuitable, and because I could afford to not work most of the time, I just went with it (for the 1% remaining, I tried a few thing, but I somehow realized they were mostly "rare/very wanted" jobs, and it'd be just wrong to steal it from people who need it.
I finally created my own small 1 guy company. But it's luxury. It's not fair. :(
