(When I became a father for first time, one of my mentor said a beautiful thing)
"I am 65. My father died years ago. On other side my kids are grown and gone. There is only one thing which matters for a man, at the end. If your children remember you as a 'one good man' who lived an honorable and honest life, they will cherish and respect your fatherhood, despite any of your flaw they know".
