You, you, you.
You are the most important thing in your world, nothing else is.
Everything, positive or negative in your life stems from you.
The most important obligation in your life is you, you owe yourself the greatest love, the biggest care, the strongest belief.
Never lose you in this self-dissolving world.
Don't confuse this with selfishness, it's self preservation. Even the greatest healer has to be healthy to cure others.
