You should never be too busy to smile, because creating happiness in your life does not take a lot of time. You just have to do a few things right.
1. Smile at perfect strangers. Don’t wait for people to smile. Show them how. Let your guard down. Talk to someone you don’t know straight from your heart. Compliment them. Don’t anticipate awkwardness. Just be you in that beautiful way only you know and give them the chance to smile and connect with you.
The more you smile at others, the more others will smile at you. And life’s a lot more pleasant when everyone around you is smiling.
