When you hate what you are doing, complain about your surroundings, curse things that are happening or have happened, or when your internal dialogue consists of shoulds and shouldn'ts, of blaming and accusing, then you are arguing with what is, arguing with that which is always already the case. You are making Life into an enemy and Life says, "War is what you want, and war is what you get." External reality, which always reflects back to you your inner state, is then experienced as hostile.
— Eckhart Tolle
