I can testify this is not the case, at least in my experience. Being able to say "I'm out" does not guarantee happiness. Compare it to people saying "when I win the lottery, all my problems are fixed". Surely you have heard about studies that conclude quite the opposite. So what makes happy, instead? Being able to cooperate with, surprise people in positive ways, and getting appreciation from that. But this also means investment: being open to ideas of others, being creative and working hard. No pain, no gain...
