I am surprised you do not find crazy to spend 10h/day + 12 in the weekend at work. It is normal for you or in your zone/country? Here in EU it would be considered madness (and legally in some states you couldn't even do it)
Of course, if you are self-employed, there is no way that those rules can be enforced… but it will be frowned upon by your relatives, because we know that it is wrong in the long term.
(I moved to work in Paris this year, so am rather interested... though I believe my 'cadre' status exempts me from this anyway)
