Start each day with a smile in front of the mirror - even if the day seems tough, let the smile give you the initial strength to face whatever awaits you.

When you see someone sad or down, be the one who brings them a smile - tell a joke, do something funny, or just smile warmly at them.

Whenever you feel you have no strength to continue, remember that a smile can be the source of joy that gives you strength - smile even when it's hard, find a small reason for joy, and see how it restores your energy to keep going.
