When you grow up, you tend to get told that world is the way it is and your life is just to live your life inside the world, try not to bash into the walls too much.
That's a very limited a life. Life can be much broader, once you discover one simple fact, and that is everything around you that you call life was made up by people that were no smarter than you.
And you can change it, you can influence it, you build your own things that other people can use.
It's to shake off this erroneous notion that life is there, and you're just gonna live in it, versus embrace it, change it, improve it, make your mark upon it.
Once you learn that, you'll never be the same again.
