what do you do when you make a mistake?

" To make no mistakes is not the power of man, but from their errors and mistakes the wise and good learn wisdom for the future."
Plutarch

I'm thinking about apologizing, every one makes mistakes. if you think about it, you have made your share of them over the years a misdirected package, a forgotten deadline.
some reactions like anger, frustration and embarrassment.
I think this is great virtue in making mistakes, learning from them and improving along the way.
when you fix a problem, you not only get a chance to right a wrong, but you can build a strong working relationship, too.
But the point is how you approach a person to apologize.
Some times saying " I'm sorry" doesn't seem sufficient, offering something extra can build good will.
I'm trying to keep a record of my errors, the causes, and their solutions.
It helps me to prevent the same mistakes.
