The birth of my second son - nothing against the first son lol, just that one was a whirlwind and hit me like a brick. The second one was just a perfect experience
Trust me, money doesn't make you happy. It may ease the pain a little. Happiness comes from things like seeing a beautiful dawn. Giving birth. Doing something good for some one else without being asked or expecting reward. There is a reason you called it 'filthy rich', think about it.
