“There is a cosmic law which says that every satisfaction must be paid for with a dissatisfaction.” ― G.I. Gurdjieff
When you are up, you think that nothing will drag you down. And when you are down, you think you are stuck there forever.
In a world that is trying day and night to keep you stuck in the lust mode, staying clean is an act of defiance.
Be nice, but never needy. Be nice, not to get something or someone, but to give. For you are a giver and not a receiver.
