It’s not that I may do it for fun precisely. I want to pay off my house, but I don’t see myself working for the next 30 years earning as much as I have been earning in the last 3 years. Economy is going bad, countries are in war, and everything is just getting harder… if I can double my income (and hence reduce by half the time I’m exposed as a worker to this society) then I’ll do it. Juggling between two jobs doesn’t sound that bad anymore.
