Willy teaches Biff that the most important thing in life is to be "well-liked." The Loman's neighbor Bernard is what Willy describes as someone who will not succeed because he is not as popular as his sons. Bernard does very well in school and Biff is failing math, which would result in him not graduating. Still, Willy tells his sons that even though Bernard has better grades, they will succeed in business better than him because they are well-liked. Earlier in the flashback, Willy mentions being more successful than Bernard's father, Charley, for the same reasons.
