This week’s challenge will make you think I’m a little crazy, but it’s also kind of fun.

Use your non-dominant hand to brush your teeth each morning.

If you’re right handed, brush with your left. If you’re a leftie, brush with your right.

What does this have to do with happiness?

It will help you be more mindful. It will help strengthen the part of your brain that handles self control and willpower. It will probably make you laugh at yourself early in the morning.

It might also make a mess.
