What's the meaning of your life?

Inspired by https://www.italki.com/notebook//entry/710327

Actually it is not the most interesting topic for a notebook entry. This subject is so stock that no one wants to read about it again. Nevertheless, now I write about it, about the meaning of a life.
Usually a person thinks about it when he or she is a child. Mostly people stop thinking about it after they have a baby (become a parent) because they have decided that the meaning of their life is to take care of (look after) the child. In Russia, where relationships between parents and their children are strong and traditionally important, it is a very popular idea. As for me, I always thought that the only meaning of a Human being is to live a fair life, to be kind to everyone and to become better every day hence the world can become a better place.
But some people don't try to seek an answer for that question, because they're too serious or they don't have time for that, they just live and do what they should do. Now I know that these people are right.
There is no meaning of a life and I'm sure that it is not a sad (bad) thing.
