There is another, deeper level of happiness, not mentioned in any of these comments. Around 62% of the US population has found it. That number used to be higher. In the tech world it's much smaller percentage. The powerful love you feel as a father or mother can actually be compounded, even when didn't think that was possible. It comes from first principles and historical truths. There is a book about it - it's the best selling book of all time.
And turns out the patterns and metaphor in this book can be co opted. Without belief in the supernatural, or submission to human authority structures. Though still receiving and giving the same benefits.
Love isn't owned by a king, it's already built in, inherent to all of us.
