Pre-Deadline
Are you (or someone you know) missing deadlines?
Use a Pre-Deadline.
In your Project Quartz journal, write down the official deadline.
Then count back 3-5 working days, and write down the date.
This new date is the new deadline.
If you get everything done on time, you have time to relax.
If something goes wrong, you still have a buffer to get it done by the official deadline.
