Check out Jason Ladanye. He’s a magician who uses shuffle math to place cards exactly where he wants them to be in the deck. Both impressive and scary.
Another takeaway is the jaw-dropping amount of practice he’s put into it, and his total dedication to perfection (zero mistakes allowed, ever). He speaks at length about this in interviews, and in fact part of his act is to explain that it is not magic at all, but his full commitment to mastering the craft. Something we can all reflect on.
