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.

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.

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.

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

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

Write down your barrier thoughts, and then consider ways to reinterpret the situation. In the process, ask yourself questions like... What else could this situation or experience mean? Can anything good come from it? Does it present any opportunities for me? What lessons can I learn and apply to the future? Did I develop any strengths as a result?

The practice of gratitude is incompatible with negative emotions and may actually diminish or deter such feelings as anger, bitterness, and greed.
