True happiness is an acceptance of life as it is given to us, with its diminishment, mystery, uncontrollability, and all.

Don't aim at success - the more you aim at it and make it a target, the more you are going to miss it. For success, like happiness, cannot be pursued; it must ensue...as the unintended side-effect of one's personal dedication to a course greater than oneself.

Everything you have experienced up till now is what you were born to learn about.

You can have no inner peace as long as the controls of your life are located outside yourself.

One of the highest places you can get to is to be independent of the opinions of other people.

Learn from yesterday, live for today, hope for tomorrow.

Kasser has conducted a variety of studies that found people who are "time affluent" are happier than those who are materially affluent. "Time-affluent people had more time to spend engaged in activities focused on personal growth, friends, and family and contributing to community" -- all essential factors in happiness, he explains.

The first condition of happiness is a clear conscience.

It is neither wealth nor splendor, but tranquility and occupation, that gives happiness.

Happiness is when what you think, what you say, and what you do are in harmony.
