“The way you learn about businesses is by absorbing information about them, thinking, deciding what counts and what doesn’t count, relating one thing to another. And…that’s the job. And you can’t get that by looking at a bunch of little numbers on a chart bobbing up and down, or reading market commentary and periodicals or anything of the sort. That just won’t do it. You’ve got to understand the businesses. That’s where it all begins and ends.”
—Warren Buffett.
