Keith Ferrazzi, relationship guru and NYT best-selling author of Never Eat Alone, posted a greatest-hits list last week- The Top 20 Relationship Posts of 2009.  Great on the Job’s How to Get More from Your Mentor made the list- thanks Keith!  For anyone looking for some great relationship building advice, be sure to check out the list.  Here are a few other’s I really enjoyed: Marci Alboher’s 7 Deadly Sins of Networking and How to Avoid them is a brilliant summary of what NOT to do these days in our networking-crazed race to find a new or better job, get introduced to a talent agent or meet the President of the company.  And in Maintaining Networking Momentum After You Land the Job: Liz Lynch offers some very practical advice for staying in touch and building new networks once you’ve got that new dream job.
