A smile can say a lot. If you are going through a tough time, a smile can show how strong you are today. If you’ve had an especially difficult yesterday, it will show that you are even stronger than you were before, because you got through it.
This doesn’t mean to fake it and cover up pain. It means that you should look deep down inside yourself to see the strength that you’ve gained for enduring your hardships. You should be proud of your perseverance. And after recognizing all of these powerful traits about yourself, you’ll have no choice but to smile for yourself.
