Perfection has to do with the end product, but excellence has to do with the process.

If you chase perfection, you often catch excellence.

Striving for excellence motivates you; striving for perfection is demoralizing

Perfection is not attainable, but if we chase perfection we can catch excellence.

Excellence is a continuous process and not an accident.

Just as Pollock used the drip to meld process and product, Richter 'found' and used the smudge and the blur to ravish the eye, creating works of psychic and physical power.
