One of the things that I have to constantly overcome is the desire to multi-task.
For me, the multi-tasking temptation takes the form of wanting to work on several projects at once -- even though I KNOW that focusing on ONE thing at a time is much more relaxing.
Whenever I feel this urge coming on, it's usually because I haven't prioritized my projects or tasks.
There is nothing as relaxing to your mind as a well thought out priority list...where all the things you're working on have been considered -- including the benefits of getting a project done, the urgency of the project and any consequences of not getting it done.
I just found a great free tool for prioritizing any list of projects or tasks. It's called the prioritizer from Idea Sandbox.
Check it out here
You just enter in a list of your projects in any order...and then click on next step.
It's pretty cool.
Have fun.
