“Man’s main concern is not to gain pleasure or to avoid pain but rather to see a meaning in his life. That is why man is even ready to suffer, on the condition, to be sure, that his suffering has a meaning.”
Viktor Frankl
So if your suffering has no meaning, why suffer at all? Why torture yourself for something that you won’t gain anything from? Why take possession of that which will never ever be yours? Why risk having your heart scarred for life for that one love that was never meant for you? Why wait to be with someone who does not even want to be with you?
