“H = S – F. Happiness = Smiles – Frowns. Find ways to smile and enjoy life, but don’t frown.
Don’t let small things get to you. Just figure out the best path to move forward constructively.
When you see pessimists, be glad that you are better with your optimism. Spread this thinking about optimism to young people.
After about age 23 your personality is settled and you can’t change it just with logical reasoning.”
