I have been a big fan of the various works and projects of Dave Eggers for several years. He brings a wise-yet-quirky view to things that quite often rings true with me.
Recently, Mr. Eggers won a TED Prize, and a couple of weeks ago his TED Prize Wish speech was uploaded to the TED website. Therein he tells of the history of the writing workshop 826 Valencia, and its various offspring and spin-offs. Very funny, very inspiring, and it gives me an unaccustomed level of hope for the future.
