Acceptance that we are a different person as our children. We have to let them choose what makes them happy and trust their own decisions as they grow older. As they become adult, we are here only to guide not to hold them and dictate what they should do or shouldn't because you will ended up hurting each other. Trust them and let them make mistakes if there is because that's what makes us grow. As hard as it is, they will eventually thank you for that. They won't blame you or anybody but themselves.
