If you want to forget something or someone, never hate it, or never hate him/her. Everything and everyone that you hate is engraved upon your heart; if you want to let go of something, if you want to forget, you cannot hate.
When one door closes another door opens; but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us.
Let go. Why do you cling to pain? There is nothing you can do about the wrongs of yesterday. It is not yours to judge. Why hold on to the very thing which keeps you from hope and love?
