Forgiving people are less likely to be hateful, depressed, hostile, anxious, angry, and neurotic.

Women’s magazines will often ask me things like, 'All right, I need six five-minute happiness strategies.' And I say, well, there aren’t any five-minute happiness strategies. This is something you have to do kind of every day for the rest of your life. Just like if you want to raise moral children or if you want to advance in your career. It’s a goal you pursue your whole life.

In a nutshell, the fountain of happiness can be found in how you behave, what you think, and what goals you set every day of your life.

...The more a person is inclined to gratitude, the less likely he or she is to be depressed, anxious, lonely, envious, or neurotic.

I prefer to think of the creation or construction of happiness, because research shows that it's in our power to fashion it for ourselves.

Thus the key to happiness lies not in changing our genetic makeup (which is impossible) and not in changing our circumstances (i.e., seeking wealth or attractiveness or better colleagues, which is usually impractical), but in our daily intentional activities.

Find a happy person, and you will find a project.
