The meaning of life is to develope yourself and make progress.
I asked my sister what the meaning of life was and she said that it was to be happy.
That is part of the answer but not the complete answer, I told her.
If you develope yourself and make progress then you will feel happy. Happiness in itself is not the goal.
Decide what is meaningful to you and pursue it as a goal.
If you look back on the human race for the past 3000 years, we progressed so much in terms of civilization, our thinking, and modern inventions.
When you think about where we will be in 3000 years from now, I am sure that there will be big step forward in a similar way that we have progressed.
Think of yourself and how you are part of the big picture and what you will do with the time you have.
