The fact that you are supposed to wreck your own conjecture. Your conjecture isn't something you're supposed to protect from your peers and your teacher as though it were an extension of your ego. It's supposed to get wrecked. That's okay! In fact, you're supposed to wreck it.
It's easier said than done.
We've grown accustomed to math that does the following:
"If you think that something is true, you should try as hard as you can to disprove it. Only then, can you really get at the truth and not fool yourself."This video could not have come at a better time. In fact, Derek sums up in about 4:40 what's taken me a semester to convey to my students.
