Happiness ALL THE WAY!
Albeit, if you don't have enough money to pay the bills, a moderate sized house & car, enough money to pay tuition for the kids (a luxury actually), and most importantly, retirement money then your happiness can get ground down.
Actually studies have shown certain cultures that are poor have a HIGH happy index. So it's a matter of perspective. In America, people are BRAINWASHED into feeling valid thru ACHIEVEMENT, otherwise on'es a loser..............this attitude is actually not shared by the rest of the world. When you travel around the world (like me), you realize people could care less about "Americans are #1 attitude." IN SO MANY regards, they are SOOO MUCH RICHER than us.
