From Guy Kawasaki's most excellent blog:
1. The Nine Biggest Myths of the Workplace by Penelope Trunk. Trunk, author of Brazen Careerist: The New Rules for Success, debunks some career myths. Find out why such aphorisms as "You’ll be happier if you have a job you like", "Job hopping will hurt me" and "Do good work, and you'll do fine" are not true.
2. Ten Questions With Penelope Trunk: Career Guidance for This Century, in which Trunk answers questions like "How much money does it take to be happy?" and "What's the ideal length of a resume in a world where every resume is electronic and not viewed printed out on paper?" (it's shorter than you think)
3. Make a List and Check It Twice: A Real-World Guide for Speakers and Presenters: some great tips for people who make a living giving speeches, but the tips are also useful for those of us who give talks here-n-there. (Direct link to Compulsive Obsession with Details will Save Your Neck When Giving Presentations from the blog Escape from Cubicle Nation)
4. Questions with Anastasia Goodstein, author of Totally Wired: What Teens and Tweens Are Really Doing Online. Some good tips here for YA librarians ... plus a link to a KQED interview with Goodstein.
If you don't read Guy's blog, you should.
