Another aspect of time mismanagement comes for the internet...from checking email and arts news, I enjoy the links on the righthand side of this page.
Some recent favorites not listed are Henry Fogel's new blog over at ArtsJournal: On the Record
Check it out, the guy knows his stuff and is fascinating reading.
Also, if you "heart" NY, then be sure to keep up with the Big Apple by checking out The Gothamist. These folks are fun, informative and very up to date.
So besides the television wasting my time, there you go.
