I use the term happiness to refer to the experience of joy, contentment, or positive well-being, combined with a sense that one's life is good, meaningful, and worthwhile.

All that is required to become an optimist is to have the goal and to practice it. The more you rehearse optimistic thoughts, the more 'natural' and 'ingrained' they will become. With time they will be part of you, and you will have made yourself into an altogether different person.

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

If we can accept as true that life circumstances are not the keys to happiness, we'll be greatly empowered to pursue happiness for ourselves.

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.

Happiness is not out there for us to find. The reason that it's not out there is that it's inside us.

Last but not least, the happiest people do have their share of stresses, crises, and even tragedies. They may become just as distressed and emotional in such circumstances as you or I, but their secret weapon is the poise and strength they show in coping in the face of challenge.
