Not a perfectionist?

Not a perfectionist, just going for high standards. High standards are important. Need to keep working on this thing, tweaking it, making it 'better'.
This article in Yahoo Finance identifies four signs of perfectionism:
1. ‘Not good enough, yet’
2. There’s no end in sight to a project or task
3. Keep tweaking and tinkering
4. Working late or long hours Is this you or someone you know?
