These are great tips. Probably one of the main reasons people are late is because of how they schedule their time. In Project Management it is known as left-to-right scheduling as opposed to right-to-left. If you use the former approach, you may find you never have enough time to be on schedule. Here's how to schedule right-to-left for better results;
1. Start by identifying the time you must be present...not in the parking lot, walking up the stairs etc.
2. Next estimate the time it will take you to get from the parking lot to the meeting room, etc.
3. Then estimate your drive time from your strting point to the parking lot. Consider traffic, weather, etc.
4. Next, estimate the time it will take you to get dressed.
5. Estimate the time to fix your hair, put on make-up, etc.
6. Pick out the cloths and shoes you'll be wearing.
7. Add all these times up and subtract it from what you identified in step 1. Add twenty minutes just for cushion.
8. Now you have the time when to get ready.
