If I'm feeling depressed, I'll sing.
If I feel sad, I'll laugh.
If I feel sick, I'll work harder.
If I'm afraid, I'll step forward.
If I feel inferior, I'll dress with new clothes.
If I feel insecure, I'll speak louder.
If I feel poor, I'll think of wealth to come.
If I feel incompetent, I'll recall past successes.
If I feel insignificant, I'll remember my goals.
If I feel all-powerful, I'll try to stop the wind.
If I become wealthy, I'll recall a starving mouth.
If I feel excessively proud, I'll recall a moment of weakness.
If I go through moments of greatness, I'll recall moments of embarrassment.
If excessive confidence takes me over, I'll recall my failures.
Today, I'll be master of my emotions.
