How far from perfection do you really need to aim for?

Yesterday I stumbled over the post titled 30 Tips for Church Stage Designs on churchm.ag with the following one particularly jumping out at me.

It only has to look good from 20 feet away. (Or your first row of seats.) Don’t spend hours making it look perfect from up close—no one is looking at it from there.

I wonder, in any ministry - not just stage design - how much time do we spend making improvements which no one else will notice?

How long to we tinker with the PowerPoint slides...
How long to we nudge around a picture on the flier...
How long do we stress over the details of a scripture lesson...
How long do we agonise over wording in the youth group talk...
When, from the view "the audience" will have, it will be near inconsequential detailing?

If we took the time to look at what we're "producing" from the standpoint of the congregation, would we strive for less minute perfection and more 5-meters-away-quality?
