A relentless approach to incremental improvement

This is an interesting quote about Billy Donovan, new head coach of the Oklahoma City Thunder: “relentless approach to incremental improvement.” I’m not sure why that quote strikes me the way it does, but I think it’s something any good person strives for. It’s similar to why I like the question they ask at the end of the Dan Patrick Show: “What did we learn today?” I just read the first quote in this article on espn.com.
