Turn away my eyes from looking at worthless things,
And revive me in Your way. (Psalm 119: 37)
The KJV warns against "beholding vanity." I like the phrase "looking at worthless things" better.
A footnote in the NKJV points out that the second part of the verse, "revive me in Your way," is "revive me in Your word" in the Targum (the ancient Aramaic Old Testament). And that points to some of the wisest advice I've heard: cut down on TV and read something valuable instead, like the Book of Mormon or the Bible, for starters. And if time permits, it might be OK to add a blog or two to your diet.
