@Vineeto I read your reply to @jamesjjoo whilst bearing in mind that what you are describing (the Actualism method) is something completely new, as in it is not some re-arrangement of the ‘tried and true’ ways, and it clicked.
It starts with the realisation that this moment which is happening now is my only moment of being alive, and it is never not this moment, furthermore it’s the realisation that this moment is actually happening, this business called being alive is actually taking place now.
So bearing the above in mind it is always silly to feel bad because of X, because I am wasting a precious opportunity to enjoy and appreciate life now, and as it is never any other time than now, I am wasting this precious opportunity for nothing.
