Phil Kessel's philosophy of life is simple. And like most philosophies of life, hard to realize. "Live each day to its fullest, don't get wrapped up too much in silly stuff . . . relax, have fun, don't get too uptight," Kessel said, rambling off a host of stay-positive mantras after another training-camp workout with the Leafs this week. And Kessel, who has had a reputation within some circles of the Toronto media for being uptight and brittle, may actually be following his own philosophy. He's showing his fun side more than ever to his teammates. In fact, he's taken charge of team fun lately.
