I read this from the book "Mojo: How to Get It, How to Keep It, How to Get It Back if You Lose It". The author Marshall Goldsmith said, "I've asked thousands of parents around the world this question. When my child grows up, what do I want my child to be? One word comes up in the answer more than every other word combined, no matter what country I'm in. Happy. You want your children to be happy. You want your parents to be happy. You want the people that love you to be happy. You want the people at work to be happy. You go first. You be happy. They want you to be happy. So one of the things that I talked about in the book is one of the important reasons to do this is not just for ourselves but for other people."
It is a very important message, but it took me 20 years to internalize it. Hope it comes faster for you.
