There is no more precious commodity than time. Each day has a finite number of hours and regardless how fast you work, or how effectively you multi-task, at the end of the day there are more tasks left than time to get them done. Personally, I work best by single-tasking and staying focused. However, that proves to be tricky as phones ring, emails pop up and colleagues stop by for a "quick" question or request. Trying to keep all of those "balls" in the air is beyond my juggling skills so I use software to manage my time more efficiently.
