Here are 20 + greatest pieces of wisdom on happiness that I want to share with you all.

If you want to be happy, be.
- Leo Tolstoy

The happy do not believe in miracles.
– Johann W. von Goethe

The secret of happiness is this: let your interests be as wide as possible, and let your reactions to the things and persons that interest you be as far as possible friendly rather than hostile.
– Bertrand Russell

Happiness is good health and a bad memory.
- Ingrid Bergman

Happiness is not getting what you want, but wanting what you have
- Rabbi Hyman Schachtel

The fellows who groan and sweat under the weary load of toil that they bear never can hope to do anything great. How can they when their souls are in a ferment of revolt against the employment of their hands and brains? The product of slavery, intellectual or physical, can never be great.
- Mark Twain

FIVE SIMPLE THINGS A DAY TO STAY SANE

There is no way to happiness. Happiness is the way.
There is no way to peace. Peace is the way.
There is no way to enlightenment. Enlightenment is the way.
- Thich Nhat Hanh

Happiness is a choice. Happy people know that their happiness depends on their state of mind, and that they have the power to choose their response to external events.

They avoid ‘if only’ fantasies, are grateful for simple pleasures, figure out their strengths and direct them toward achieving meaningful goals.

They’re engaged in their work, look for ways to get more pleasure out of life, and are kind toward others.
- Marelisa Fabrega

To be without some of the things you want is an indispensable part of happiness.
– Bertrand Russell

The greater part of our happiness or misery depends upon our dispositions, and not upon our circumstances.
- Martha Washington, Wife of George Washington

Remember the old Scottish motto: “Be happy while you’re living, for you are a long time dead.”
- David Ogilvy

ACT HAPPY.
We can sometimes act ourselves into a frame of mind. Manipulated into a smiling expression, people feel better. So put on a happy face. Talk as if you feel positive self-esteem, are optimistic and are outgoing. Going through the motions can trigger the emotions. Count your blessings.
- Psychiatrists
