Some of the best and most simple time management tips that have helped me, include:
1 - keep phone time limited; multitask when it is possible
2 - have an agenda for meetings, to keep from running over
3 - be direct, simple, forward
4 - use email as much as possible, over the phone, where ever you can. the phone is an enormous time waster; people are encouraged to blather on and on, whereas, with email, it is easier to be direct and to the point. also, with email, one can save messages and information which may later be used in reports, lists, etc.
5 - plan your next day out, by the end of each day; that way, the next day's activities are at the forefront. prioritize by the most important things
6 - schedule work as much as possible
good luck!
