Like other characteristics, I've had to give this a lot of conscious thought,
because my natural tendency appears off balance.
Not quite a perfectioninst, but very high standards and ambitions once I've engaged with the idea that something actually needs doing (that.s a separate isssue)
It hits particulary with things like DIY and hobbies where the finished result, however praised by others, never matches my original mental concept.
Over the years I've given myself a lot of talkings to, and can now, as well as
"If a job's worth doing, it's worth doing well, " also countenance
"If a job's worth doing, itts worth dping badly."
The engineer's idea that if you do a better job than you need, it's wastefu,l has also been useful.
