Why to learn?

You should learn because actually you have no job and you are still living with your parents.
You should learn because life is not about how you look in the eyes of the world,stop running to invent yourselves,adopting an image and style is not a way to accomplish yourself.
Don't excuse yourself that some people are born smart and others are not.Nobody comes in to this world already taught. There are some people with a genetic predisposition to learn faster and better,that doesn't mean you're stupid.
By learning you are actually acquiring a tool , a tool that improves your understanding of the world and the resolution of problems.
Nothing is complicated, you just have to work a little.
To learn doesn't mean you have to become a dork , a geek.

And I forgot ,you don't have to become a university professor. Learn as much as to know at what use you can put the tool and to get an image of the purpose. When you'll need to use it ,it will happen fast.
