If you have had an unfortunate experience, forget it. If you have made a failure in speech, your song, your book, your article, if you have been placed in an embarrassing position, if you have fallen and hurt yourself by a false step, if you have been slandered and abused, do not dwell upon it. There is not a single redeeming feature in these memories, and the presence of their ghosts will rob you of many a happy hour. There is nothing in it. Drop them. Forget them. Wipe them out of your mind forever. If you have been indiscreet, imprudent, if you have been talked about, if your reputation has been injured so that you fear you can never outgrow it or redeem it, do not drag the hideous shadows, the rattling skeletons about with you, Rub them off from the shite of memory. Wipe them out. Forget them. Start with a clean slate and spend all your energies in keeping it clean for the future.

We do not have to live the same mistakes over again if we can look at them, learn from them, and build upon them.

Forgetting your mistakes is a terrible error if you’re trying to improve your cognition. Reality doesn’t remind you. Why not celebrate stupidities in both categories?

The only way to get rid of your past mistakes is to learn its lessons for the future; God will waste nothing. Make every experience count.

The urge to catalog the myriad blunders in order to “learn from the mistakes” is for the most part an exercise in denial and self-deception.

If we experience any failures or setbacks, we do not forget them because they offend our self-esteem. Instead we reflect on them deeply, trying to figure out what went wrong and discern whether there are any patterns to our mistakes.

If you live long enough, you'll make mistakes. But if you learn from them, you'll be a better person.

You may have noticed students who just try to remember and pound back what is remembered. Well, they fail in school and in life. You’ve got to hang experience on a latticework of models in your head.

I can't erase the past, only learn from it.

They will very probably, by remembring past mistakes, avoid many inconveniencies into which forgetfulness will run you lively ones.

We want to learn the lesson and not repeat the experience. But in truth, we do not like to look too closely at what we did; our introspection is limited. Our natural response is to blame others, circumstances, or a momentary lapse of judgment.

One cannot too soon forget his errors and misdemeanors. To dwell long upon them is to add to the offense. Repentance and sorrow can only be displaced by something better, which is as free and original as if they had not been.

Mistakes make you human. But the point is, how do you look at your mistakes? What are they there for? Nobody is infallible. You are going to forge ahead based on what you have learnt from them. When you fall down, you have to get up. Learn your lessons, get up and keep going even stronger.

When you tolerate an error, you rob yourself of learning.

When you ruminate on an error, you rob yourself of happiness.

Notice it, improve it, and move on from it.
