No, the entire setup I have is geared to function as company: I have many clients (who keep coming back because they can kick me out any time which is a bit of an issue in the EU, but then they don't) and I also make products which even more cements me as 'defacto employee'. I had many discussions (especially) with the dutch taxes who tried to catch me out; never worked.

Pretty cool, thanks for sharing with us! It originally sounded like you were earning this from a specific job, but yes if you can build a successful business then your earnings can get arbitrarily high. I'm not sure most of us would describe it as "not hard" though! Congrats!
