Well i'm 36 married with 3 young kids and a great wife, i wouldn't change it for quids.
Having said that i caught up with a mate i hadn't seen for a few years last weekend who is the same age. He isn't married lives the single life in syd owns 2 houses and roots asian hookers whenever he pleases, it left me wondering who made the right call ???
Elvis had money, fame, women , every thing in life a man can wish for yet he resorted to drugs and died a miserable death.
May be your friend is not happy with 2 houses and rooting asian hookers, may be he looks up to another guy who is more richer and roots even better asian hookers than he does.
It is all about what you are contended with.
human desires are endless and there will always be someone more healthier, wealthier, and with more asian hookers.
