I would add 4:
1. Talk to your Top 5 Customers. Either invite them to a Networking Holiday Party or have a private one of your own to find out their plans and how you can help them more in 2011.
3. Sales Performance Review of your team that includes going over wins, losses and improvement. This is the beginning of your Sales Planning for 2011.
4. Talk to a few prospective strategic partners about ways to work together in 2011. Data backup, cloud, Manged services, PC support, or VAR's as a sales force - just a few ideas.
Happy Holidays and thanks for reading.
