His retirement letter: In a letter to newspaper editors announcing his retirement, Watterson stated: "This is not a recent or easy decision, and I leave with some sadness. My interests have shifted, however, and I believe I've done what I can do within the constraints of daily deadlines and small panels. I am eager to work at a more thoughtful pace, with fewer artistic compromises. I have not yet decided on future projects, but my relationship with Universal Press Syndicate will continue." Fewer artistic compromises apparently means living off his millions.
