Learning how you learn best might be the best thing you ever learn. Some learn by reading, others learn by listening, and a lot of us learn the hard way. But, make no mistake, if you know better and choose not to do better, that's not "the hard way" β that's just being a dumbass.
A fact is information minus emotion. An opinion is information plus experience. Ignorance is an opinion lacking information. And, stupidity is an opinion that ignores a fact.
