What if the person who made you smile is also the person who hurts you? Why wait for someone to make you smile? Rock your own positive energy and smile to the sky.
"Don't cry because it's over. Smile because it happened." - Dr. Seuss
its true, Good thoughts leads to happiness, bad thoughts leads to doom.
Always Do Your Best. Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best, and you will avoid self-judgment and regret.
