David Foster Wallace is the much-celebrated author of the one thousand-page plus novel “Infinite Jest.” Not an easy read. But then, neither is “Ulysses,” or “Gravity’s Rainbow,” George Perec’s “Life: a User’s Manual” nor any number of boundary-blowing, epoch-making masterpieces that we crack open from time to time and know we will read some day. “Infinite Jest” I’d already given up on and picked up again several times.
