Challenge 13.

Make an effort to smile at someone every day. It can lift both your and their mood.
Wearing a smile each day is akin to giving your brain a cheerful high-five, creating a sensation as if you've just triumphed in a game of hide-and-seek with joy!
Additionally, it leaves your frown lines puzzled, wondering if they should consider a vacation rather than preparing for a long stay.
So, show off those bright smiles and let the world see that you're geared up to tackle the day like an energetic squirrel.
