More zeroes, love or drugs won't make you happy. But all three together works pretty well.
They are fine things to have, and it can be fun to try to make more money just to see how high you can push that number. It's foolish to think that hitting $150,000 will be much different from $75,000, or will bring you any more real happiness.
Keep it light, keep it fun, keep non-emotional in the treadmill and see it for what it is.
