Never grow above the stage where you can never apologize to someone whom your actions might have hurt them in one way or the other. Apologizing when you are at fault has a way of building you a good reputation. By saying you are sorry, it means you've accepted the very fact that you were at fault and you are willing to change. This helps in building trust between you and your clients, employees, family, friends etc. Never hurt people with your actions and turn away without saying 'sorry'. Showing remorse by apologizing means you care about people's feelings and you are human enough not to trample on it.
When I was a child, being beaten by mom or getting offended by any other person, I'll cry endlessly till I get a 'sorry' from the person. This was always like a healing balm, immediately the person apologizes, the tears will be nowhere to be found. Till now, 'sorry' remains an essential healing pills for children.
Never allow the height you've attained in life to destroy your personality.
Apologizing causes zero harm.
Learn to say 'I'm sorry' when you should.
