I've long held that goofing off, time wasting, and procrastination may not be all bad. They may have a worthy purpose. There's something about those times when the mind is engaged in something light, frivolous, or easy that allows us to rest, or think, or plan. There's something about idle or semi-idle moments that kicks the creative mind into gear, behind the scenes.
Like anything, goofing off can be carried too far.
But we're not robots who can fill every moment of every day with
productive activity. Maybe the reason the brain often leads us down
these distracting little side paths is that we need some distracting
little side paths.
