Very interesting perspectives; thank you all for sharing. Success will always mean different things to different people, but it seems like in a capitalistic society, it means having a rewarding career--whether it's a high-paying job or a position that has a lot of prestige.
One of my favorite quotes (by Elbert Hubbard):
He has achieved success who has worked well, laughed often, and loved much.
Also, doesn't success involve satisfying your goals or objectives? If your goal is to own a home and you've achieved it, then you are successful in that regard.
