Stop beating yourself up about things that have been and gone. We all make mistakes. The past is dead, so why do we keep bringing it back to life in the present? Why do we keep carrying it on our backs, only to suffer under the weight? We cannot change anything. Nor should we regret anything. Everything is a learning curve; even steps backwards are actually steps forward. Stop living in the past and work on being a better you in the moment you’ve got.
