I tried for years to learn magic from books, starting in elementary school when my folks bought me a great kid's magic kit for Christmas. I could never quite figure out how to make a sleight last more than 30 seconds, even though I kept reading and trying through high school, even as late as in law school. The Royal Road, Bobo's Modern Coins, you name it. I never got anywhere and eventually gave up.
For my 49th birthday, my wife bought magic lessons for me. It had been so long since I even tried, I showed up for Aaron with zero percent "Technique" and zero percent "Misdirection." My training as a lawyer may have left me with some ideas for structure and presentation, but basically I was at ground zero.
