You've likely heard "fake it til you make it"...well, Mark has done that, and talks about it here.

[00:00] So, one day at lunch, this is the the [00:02] first time I'd done this, I thought, [00:04] "Oh, maybe I'll go back to the computer [00:05] lab [00:06] uh and see who's around." And when I got [00:09] there, the the lab manager [00:12] had told me, "I uh you know, one of our [00:15] professors uh got ill and like class was [00:18] starting in a day or two. And this lab [00:21] manager friend told me, 'They're going [00:22] to make me teach the course for him. You [00:24] know, they're desperate, basically.' And [00:26] he said, 'Mark, would you would you [00:27] please do it cuz I I definitely don't [00:29] want to do it.'" [00:30] >> Called the great Mark [00:31] >> I can't do it. I'm I was a student here [00:33] like a year ago." But then I went home [00:35] and I thought about it and I thought, [00:37] "Uh [00:38] might look good on a resume to say I, [00:40] you know, I taught a course one time." [00:42] So, I forced myself to do it and it [00:45] actually went great. I I know this term [00:48] wasn't used back then, but fake it till [00:49] you make it. I I definitely decided I'm [00:52] going to fake it. I'm going to pretend I [00:54] know what I'm doing and the students, [00:56] they couldn't tell. They just assumed I [00:58] knew what I was doing.
