Make that idea your life
Life is a series of natural and spontaneous changes. Don't resist them - that only creates sorrow. Let reality be reality. Let things flow naturally forward in whatever way they like. Live each day as it were your last.
You only live once. Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Believe in yourself! Live each day as it were your last. You only live once.
