All I have learned, I learned from books.

Get books, sit yourself down anywhere, and go to reading them yourself.

A capacity, and taste, for reading, gives access to whatever has already been discovered by others. It is the key, or one of the keys, to the already solved problems. And not only so. It gives a relish, and facility, for successfully pursuing the [yet] unsolved ones.

I never tire of reading Tom Paine.
