Laughter is more than just a pleasurable activity...When people laugh together, they tend to talk and touch more and to make eye contact more frequently.

Guard your children's free time - from you.

I think self-knowledge is a key to happiness.We can build happy lives only on the foundation of our own natures, our own values, and our own interests.

Say “no” only when it really matters. Wear a bright red shirt with bright orange shorts? Sure. Put water in the toy tea set? Okay. Sleep with your head at the foot of the bed? Fine. Samuel Johnson said, “All severity that does not tend to increase good, or prevent evil, is idle."

Relationships make me happy.

Your unhappiness doesn't help anyone else - and in fact, as I mentioned in another answer, happy people are more altruistically inclined. So happiness is not a selfish goal.

Contemporary research shows that happy people are more altruistic, more productive, more helpful, more likable, more creative, more resilient, more interested in others, friendlier, and healthier. Happy people make better friends, colleagues, and citizens.
