I will ask and answer another question that isn’t directly addressed in the video.
The most important thing, I would think, is to realize that your contrary opinion is probably something that the others are fully aware of. They’ve heard it before, almost certainly. And even if they don’t hear about it from you, depriving the group of your particular stellar idea probably won’t do anyone any harm. In other words, as exciting and compelling as your thoughts are to you, in all probability they aren’t that novel or important.
