John is the single-most self-motivated person I know. He is, in my opinion, off-the-charts brilliant, and I do not use the term loosely or ... metaphorically. Everything he knows about computers and coding, which is enough to have rocketed him from entry-level to managerial level almost immediately at his job at Deltek, is self-taught. If John is curious about something, he sets out to learn and soon becomes an expert. If you were to see his library (which used to literally fill his apartment before he went digital), you would begin to get a glimpse of what I mean. Furthermore, John is intellectually honest in a way very few people are: when he is grappling with an idea or area of interest, he courts contrary opinions and engages in debate where no cows are sacred. His ability to look at and through his own confirmation bias and change and adapt his ideas based on other thoughts and ideas is truly remarkable. And debate with him is challenging and rewarding, because of his ability to find other people's confirmation bias and challenge them--always with civility and respect and never personally, but with a clarity and precision that fosters intellectual growth and synthesis in those around him. I cannot imagine a better person to have on one's team.
