We make choices. That is a fact. I don’t consider we make mistakes because when we do something it suits at that moment.
Everyday we make choices and as easy as it is in hindsight to say we should have done things differently, it is not so easy at the time.
Never regret the choices you made. First of all, you cannot roll back and change the past. Instead, consider the choices you made suited you for that moment.
Never live with regret but instead live with the choices you felt suited you at those past times.
