Good words to remember. It really applies to every facet of video creation too. For instance, when doing a gaming video you often find yourself wanting to show just the right scene, just the right angle, or say just the right thing about the game you're playing, as you're playing it. This can lead to trying to record the scene quite a few times until the recording no longer really sounds natural. Of course this sort of thing does smooth out a bit with practice, but keeping what you said in mind would help even more.
