Part 8/9:
Don't compare yourself with anyone, if you are doing this, you are insulting yourself. If you don't have any shadow, you're not in the light. If you want to fly with the Eagles, you have to stop swimming with the Ducks.
Your children will follow your example, not your advice. The art of being happy is to be satisfied with what you have. Stop worrying about people who are not worried about you.
Never regret anything that has happened in your life, it cannot be changed, undone or forgotten, so take it as a lesson, learn and move on. Sometimes painful things can teach us lessons that we didn't think we needed to know.
