Do not tolerate task bloat. If it takes less than a few minutes to do or delegate, act on it right away.
Too often a task will wait, and in doing so you remember it, think about it, and at some point, the idea of the task will have consumed more time than the task itself would take to complete.
“If an action will take less than two minutes, it should be done at the moment it’s defined.”
~David Allen, Getting Things Done (Book)
