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.
Letting go means setting free,not only of someone but of something pertaining to the said person.That way, you will find a free space where you can do what you want and have enough time to think and realize what you really want to be.
