Know that you are a student forever. Do not underestimate anybody. Knowledge may come to you from any corner. Remember the ancient saying - let knowledge flow to me from all the sides.

Each occasion teaches you and each person teaches you. The world is your teacher. When you are always looking to learn, you will stop underestimating others. Humility will dawn in your life.

There is a nice story. A man earned a lot of money and then gave all his property to his son. The son then built a small house behind his big house and told his parents. Now you have to stay there. So the old couple stayed there, while the son and his family lived in the bungalow. 

One day, while playing, the grandchild came to his grandfather's home, where everything was in pathetic condition. The grandchild said, Grandpa, be careful with your plate and chair. Don't break them. 

When he asked why, the child said, because tomorrow, my father will need them. One does not realise this fact. You are also going to be old one day.
