How to make my mother smile ?

This is the most difficult , challenging yet simple topic I have ever encountered with to share my experience. My mother, if I had to describe in one word would be fighter. Since her childhood she has been fighting one thing or the other. Then married to a orthodox family, their she had to fight for her rights, then gave birth to daughter, then for her rights she had to fight. Since the day I have started understanding things, I have always seen her fighting for either her rights or my rights and freedom. Whether it be against my father or my grandparents. But one thing which is common everytime is smile on her face. In most difficultest situation too, I have never seen smile off her face. She believes and always teaches me that whenever problem comes in your way and you find no solution, just smile, problems will go miles away. I don’t know how to make you smile ? What to do ? All I feel I can do is one promise that I shall leave no battle midway and win over all problems with smile on my face.
