How much money do you have in the bank? If you stop working now, how many years could you live with that money, in a decent cheap house (in a cheap part of your country, not even in a cheap foreign country) Remember you do not have to work: so no transit, no representation shopping, plenty of time, so you can enjoy repairing broken furniture instead of replacing it, you can enjoy cooking instead of going out, etc.. You can fish, but will more likely buy fish... fish are cheap. How many years? Those years measure the part of your income that go into paying for the obligatory expense your working lifestyle impose upon you.And that's my only argument: money you get from work is overrated, it is mostly useful because you work. There must be a case for a sustainable innovative world where we work 15-10-5h/week. But obviously we will be too bored to indulge in it.
