I've found that I snack less and concentrate better when I chew on a plastic stirrer - the kind that you get to stir your to-go coffee. I picked up this habit from my husband, who loves to chew on things. His favorite chew-toy is a plastic pen top, and gnawed pen tops and little bits of plastic litter our apartment.

Act the way that you want to feel.

People feel happier when they feel like they're progressing. When they feel like something in their life is growing or getting better.

No one regrets having changed a lightbulb.

Now that I've relinquished my fantasies of all the people I wish I could be, and stopped feeling guilty about not going to the opera or pretending that I want to attend a foreign policy lecture, I have more time for the things that I truly enjoy.

One of the best ways to make yourself happy is to make other people happy. One of the best ways to make other people happy is to be happy yourself.

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.
