One Minute Tasks are a good habit to get into
An example:
It makes sense to check for urgent messages first thing in the day, but it may not always be possible to do a full Daily Check. For example, on Tuesdays, you may have a meeting with your mentor first thing in the day. In this situation, a one minute task on your schedule will act as a reminder to check for any urgent messages before your meeting. This approach - scheduling a one-minute task whenever you have to disrupt a regular routine - is a good way to avoid things getting forgotten in the swirl of the busy day.
The alternative is that standard tasks get overlooked when urgent tasks crop up.
