The ability of discerning high quality unavoidably implies the ability of identifying shortcomings.

Raise your quality standards as high as you can live with, avoid wasting your time on routine problems, and always try to work as closely as possible at the boundary of your abilities. Do this, because it is the only way of discovering how that boundary should be moved forward.

Only the best is good enough.

I wanted it to be like a high quality, drive-in movie.

Commit yourself to excellence.

I collect LPs, but only if they're pretty high quality. I don't go back and dig through the bins.
