Time heals almost everything. Give it time.

Let it go. 

No wonder people in this world are many times unhappy. I admit that one can count me among these people. The main reason people are not satisfied is the fact that they are not ready to let go.
A universally acknowledged fact is that it is extremely difficult to leave behind past mistakes. Instead of learning from it, people keep wishing that they could change the reality. It seems impossible for them to stop dwelling on the past mistakes. Errors do happen in everyone's life. It is just a hurdle. Even if people do not recognize this at the point, with time they realize that actually their fallacy was a lesson by life.
At some point in our life, we feel as if we are betrayed. Rather than forgiving the person, we keep holding the grudge. We lose control over our ability to stop the wound from hurting us further. We fail to recall that leaving the wound undisturbed is the only way that it will heal over time. Wait patiently; time heals the wound and nothing is left but a faint scar. Time is indeed a medicine for most of our problems. Holding grudges, retaining your ego and  escaping, won't help. It is important to understand that ," Time is the wisest councilor " -as said by Pericles (the influential ancient Greek statesman and general). With time people understand and learn to accept. Time gradually heals most of our wounds and gives us the power of clear reasoning. We learn to see what we are looking at. We start seeing people and things for who they really are. We understand and with time most of our wounds heals because of our ever growing wisdom.
