Find one way each day to make someone else smile – with a joke, a compliment, or a kind glance. It's simple, and it's contagious.

When you catch yourself sinking into excessive seriousness – take a moment, look for something funny around you or within you, and laugh wholeheartedly.

Write yourself a list of 5 things that bring you joy and laughter – a movie, a person, a memory, a song. When it's hard – open the list and choose one of them.
