A kid is the reason not the result

For the most part people get married because they want kids. Kids don't come because people get married.

You marry because you want to live with the love or your life or whatever other reason is ..but let's face it, the bottom line is a kid.

why?, easy .. everybody loves kids , for people they re the reason to live for.

they cause parent unbelievable happiness. they want them because they make their life make sense. they are the major achievement for parent.

question : what's next .. you have your kid .. so what ??
answer : what a question.. that's it .. I have a child.. my life is full of joy.

question : what about his life.
answer : he will have good life .. we are going to do our best.

They really do their best for him, they do variety of things. more or less the same what has been done to them by their parents

Kids grow and get married and the cycle repeats.

that's great .. but is that enough??

For the most part : NO.

how doesn't want his child to be a genius? like Einstein, or Beethoven, or Picasso? who is happy with what he is and don't wish he was better person?
If you are then stop reading .. that's it for you.

the general believe that life is what it is and time to time a genius will be born and makes it different (in general better).

That's wrong. exceptional talents are not born.. they are made.. more or less.
If you know how to do it then start now.. if you don't then don't have a child before you learn how to make him a genius.
