There is. You just can’t be excellent at parts that are constantly changing. Avoid those who bumped more than 3 versions in a decade, they aren’t confident in what they want.
Excellence is a trap. It leads to hubris. An excellent programmer can be really annoying, and excellent code is unnecessary.
Instead of excellence, strive for "working code", collaboration, quality, velocity, improvement, shipping the right thing at the right time. Use debt wisely and move forward.
Right he's talking about a developer who is caught in the trap.
A better way to put it, is a developer about thinks he's excellent. What someone thinks is, the majority of the time, not inline with what he actually is. Especially for developers who think they are excellent. Looking at you Brian Camacho.
