I wish happiness could be purchased by money; then, I'd steal a couple of millions and stay happy. Sad truth - happiness is not constant, it comes and goes.
But still it made you happy right? Nowadays, it's not easy to be happy when you don't have money. Almost everything that could make you happy can be bought (if you are a loner).
If you want to be happy without money then I think it's time to leave your job, stay in the jungle along with people who survive because they are stretching their muscles to catch their food and they are away from civilization, then probably money is not important to them.
