listen to stinkpaw.
my own experience: i was a lawyer for nearly two years before i quit to play poker fulltime. at the time poker was just a convenient exit strategy from a hellish existence working my arse of in a commercial firm doing stuff i had no interest in and not even getting paid very well based on my hours worked. plus i got shat on at every possible corner by someone who was higher up than me and getting shat on by someone higher up than him...and i was working in one of the comparatively laid back firms!! also in terms of interest in law, i found studying law ten times more interesting than the actual work. working is just basically keeping clients strung along and paying the fees, while pushing paper around and setting dates and all other administrative garbage, with a tiny bit actual real "lawyer" type work, at least that was my experience. i imagine it could maaybe get more interesting and "fulfilling" at the higher levels.
long story short, im a lot happier as a moderately successful small/midstakes grinder than i ever was as a young up and coming lawyer. i really hope to take it further and move up and make a ton of money, but so far it was the best decision i ever made.
oh and btw, rofl at the whole "contributing to society" argument in favour of doing law. if you do end up becoming a lawyer, in particular a commercial lawyer, you will come to appreciate why i find that argument so hilarious.
gl with whatever path you choose, even if it is law
