a spoonful of

there's this guy i know. i feel so bad for him because he's such a slacker and everyone knows it. why he refuses to change, i'm not sure. the fact that he refuses to change makes me feel like something is really mentally wrong. most people want to go out and make something of themselves. it's a great feeling to be able to provide for yourself. for those who don't care to work hard and make an honest living, i wonder. it's different for men than it is for women because i think that a lot of people look at women as the ones who need to be taken care of and it's somewhat socially acceptable for a woman to live at home till marriage (not feeling that for real but it is what it is). whereas if a man doesn't go out and find a job and his own place, he's not a man. my question is this: those people who watch life go by, don't work, don't strive for anything but mediocrity, live off parents when they're fully capable of taking care of themselves, make countless excuses for constantly mooching, make excuses period, are these people plagued by personality disorders? or are is it an extreme case of laziness?
now, i'm not talking about folk like myself who have been unemployed and forced to move back home due to the economic state. that's happening literally everywhere. i'm grateful it's just me and that i don't have a husband and kids to support like many many others out there. but even still, though there's a recession, there's always something to do. i was able to get freelance work and i'm also in school. even if you subtract the financial aspect, why not find a way to develop yourself? learn a new program, learn how to forecast, pick up an instrument, learn to cook, read the Bible.
at the end of the day, are there more people than we think with personality disorders that prevent them from being "successful" or better yet, self-sufficient? Or...are people just lazy?
