At one point I realized I was trying to list too many detailed actions for each project. Then I came up with this simple guideline:

Each task should be a complete action that advances the project when done no matter how much time passes between it and other tasks. If a delay between two tasks means the first one would need to be redone then the two tasks should probably be combined. The only caveat is if you're intentionally trying to capture a tedious list of steps to make sure nothing is missed or done out of sequence.

For example...
Project - Wash car
Task - Find keys
Task - Pull car into driveway
Task - Carry hose to front yard
Task - Wash car
Task - Put car away
Task - Put hose away

If I do the first task of finding the keys and then I get distracted and work an a different project for the rest of the weekend I'll have to redo the first task again as if it had never been done in the first place when I come back to this project.
