“Mistakes were mistakes, and failures were failures. Why torment someone with memories of their past?”

“Philosophers' Syndrome: mistaking a failure of the imagination for an insight into necessity.”

“Some of the best lessons we ever learn, we learn from our mistakes and failures. The error of the past is the success and wisdom of the future.”

“When I look at my life I realise that the mistakes I have made, the things I really regret, were not errors of judgement but failures of feeling.”

“Failure is not fatal nor that you are finished but the result of unfinished product waiting to be reproduced, reprocessed and polished. Failure is that you have learned your omissions, mistakes or what you did not do right or well at the last attempt. You can transform failure into a fortune by dealing with what went wrong. Failure is only a product of uncorrected mistakes.”

“Do not brood over your past mistakes and failures as this will only fill your mind with grief, regret and depression. Do not repeat them in the future.”
