It's all relative, I have a brother who is a professional dive guide on Guam, I would guess he makes ~$20-30k year but her is the happiest SOB I know.
I have friends in the states who make $200k+ year and live in huge gorgeous houses and are absolutely miserable.
I am lucky, I do something I love and make a mediocre living, I can buy supplies for my hobbies and have a few nice things but not much more.
In the words of the great Dennis Hopper, "You gotta simplify man".
It is not about the dollars, it's about what is in your heart. Just don't become a burden on society, that's all I ask.
