I keep a separate list call @DEADLINES where I keep all of my due date information. It is part of my daily routine to check that list. I also have the option to put them on my calendar if I want to add an extra layer of security

HINT:
NEVER plug in self-imposed deadlines for projects. Way too easy to do, and it is waaaaaaaaaay to easy to just blow them off. If you start to ignore those deadlines, you will ignore most of them (now which is a real deadline and which is just "like to finish by"?)

Only use REAL deadlines:
- I promised by customer they would have it by
- The presentation is scheduled for
- I will get fired if...
etc
