“Always forgive, but never forget, else you will be a prisoner of your own hatred,
and doomed to repeat your mistakes forever.”
Wil Zeus.
("Wil Zeus is the author of Sun Beyond the Clouds and he is a student of life in a world full of it").
This phrase appears many times when searching for self improvement quotes.
I am ok with the first part of it, however, when someone repeats mistakes forever,
the cause is probably different than forgiving and remembering.
More than that, being a prisoner is, in my opinion, related to obsessions disorders.
