Meaning of life

 I hear a lot of people wondering: "What is the meaning of life ?"

Also a lot of books were written on this subject.

My opinion is that you will know the meaning of your life, when life is almost over.

Then you will look back an say "I did this and this and this is the meaning of my life"

Till then focus on the present. In what you should do now and not regret tomorrow.

The whole life is a sum of "now"s.
