From a euro pov.
I can ( with ease ) put around 3000 euro aside to pay off that horrendous flight school loan. Currently after all my deductions (car/furniture/PS) I receive around 6-7k a month.
This month I did 105 hours ( YES! No sarcasm, actually happy ) so that results in: 8614 euro Net. ( with my wifes addition it'll be over 10k)
I have no kids, as above mentioned my wife works and I live a normal / poor lifestyle in order to pay off my loan asap.
