You've probably heard it said that mastery takes around 10,000 hours to achieve, as written about extensively by Malcolm Gladwell in Outliers. Imagine you want to become a master filmmaker and you spend eight hours a day practicing your craft. In 1,250 days or roughly 3.5 years, you should arrive. But the reality is that many of us, myself included, don't spend that amount of time each day on the things we want to master. Instead, we watch a few YouTube videos, poke around in our software, buy a bunch of positively reviewed gear, and naively proclaim like Neo in The Matrix, "I know kung fu." But for every subject we claim to know, there will always come a time when someone says, "Show me."
