"I have a book."
It's...sort of my standard answer for everything.
"How did you learn to..."
"How do you know what..."
"I have a book"
Books are extraordinary.
You only have to be able to read them and you can learn basically everything.
It's amazing.
They don't judge you, they don't make you feel stupid, they are very patient and understanding and they support you, always.
So when you want to understand or to learn something new you just have to find a book or two. Maybe more.
That's it.
