Marci Alboher has a great post on her Shifting Careers blog which gives 5 tips on time management.

1. Tame the Email Beast. [Have you read Bit Literacy?]
2. Eliminate unnecessary meetings. [Sometimes a meeting isn't necessary when there is nothing but a recap or review]
3. Put up boundaries.  [Get off the IM/Facebook/Google Chat when you have to focus on one thing]
4. Find your rhythm and schedule around it.  [A CEO friend of mine believes in following your biorhythms to be more productive.]
5. Say no. [This is the hardest one for me, but the holidays have forced me to start doing this now.]
