This is so true.
We have to learn everything, even if we never use it again probably!
I used to be so angry because of this, learning BS taking my time in which I could have learned much more interesting and important stuff. But now I just accept it because we can't do anything about it.
You never knows when you will need your knowledge. Steve Jobs learn calligraphy just for fun; who knows he will "create" Apple after some years and use those calligraphy for his inventions ;)
Just be equipped and find something you are passionate about would be great enough
Thanks!
This is very inspirational!
