What you call "semantics", I call "a critical distinction" that needed to be pointed out. In my early years, I wasted a lot of energy trying to be more productive, efficient, effective, (call it whatever you want), until I learned one of the most valuable and counter-intuitive lessons of my career: it really doesn't matter how "good" you are, how "well" you work, or how good you "feel". All that really matters is whether or not your cumulative contributions keep increasing. Take care of that and you won't have much else to worry about. Don't do that and you'll end up worrying about all the wrong things.
