"I am not the type of person who thinks in terms of "if only" or "could have, would have, should have". It is what it is and everything happens for a reason. When a person thinks "if only I would have known such and such" it shows a certain amount of fear or lack of trust that everything is as it should be. I try to always do my best and if I look back and think I didn't do my best, then that is the only thing I acknowledge and then try to change. One of my favorite expressions is, "Everything is okay in the end and if it's not okay, it's not the end.""
