well, i hope this somewhat serious post doesn't knock things out of whack...
my wife and i both worked in nyc (we met before that). she decided she hated the p.r. / advertising world, and wanted to become a teacher - giving up (little) money for (littler) money and stuff. we weren't married, were living together at the time...knew marriage would come at some point, and i supported her in her dreams.
i knew i had to give trading for myself a shot at some point, and though i didn't have quite enough money aside yet, left my job (2 people in my group were directly responsible; if it was only on end users, i'd have stayed). had some struggles. she supported me in my dreams.
we now have a daughter...she's still teaching (afternoons, as i trade aggressively in am). and we're both loving what we do.
