you're tired? you wanna quit? sure, go ahead. in a few years' time, when your wife gets tired of waiting for things to get better, when your parents need support and you wish you could do more for them, when your friends are traveling, building, living, but you're stuck working job to job, when your kids are asking for things you cannot give them i hope you have the decency to tell them that their lives are miserable because you gave up.
