If you did something wrong and your attention is called upon for corrections, never try to defend it, accept that you're wrong or that you made a mistake, the fact that you've accepted mistake won't kill you.
If you intend to do something and you don't know the right way of doing it or the right path to follow seek advice from a friend or someone that would tell you what to do.
Sometimes you might not know if that person or friend is an expertise in such area or if that person has experience about that same thing you intend to do.
As a leader, don't be to proud to seek for directions/advice from a friend or your or your follower. If the masses correct you and call out your inadequacies, accept it and hard to fix your mistake(s).
As a husband, if your wife calls your attention upon for corrections, accept your mistake and accept such correction, it won't stop you from being the husband.
Parents, if you're wrong and your kid(s) try to correct you, listen to them, if there's a bit of sense in what they have to say accept it. This will even make the family bond stronger.
Teacher, if you're wrong and your student corrects you accept it, teachers do learn from students also.
The only time you shouldn't accept your mistake(s) is when you're quite sure that you're right and can prove the other person wrong.
Accepting your mistake(s) and correction shows how discipline, loyal and humble you are. This also makes life easy.☺️
