focus in his work. Not only does high intensity allow him to make progress more quickly, but long hours are also critical to maintaining a focused mindset over time. Despite working such a demanding schedule, he has never experienced burnout. Carmack is also known for taking week-long programming retreats. These retreats involve a solitary, uninterrupted period away from his normal routine often sequestered in a random city and hotel. The goal of these retreats is to allow Carmack to operate at full cognitive capacity, tackling a specific, difficult problem or learning a new skill. The solitude and physical isolation of these retreats offer the perfect environment for deep focus and reflection, making them an essential part of Carmack's creative process. Carmack was vocal about his frustration with the bureaucratic inefficiencies he encountered during his time at Meta. In his departure memo, he stated, "We have a ridiculous amount of people and resources, but we constantly self-sabotage and squander effort," he wrote. "I have never been able to kill stupid things before they cause damage, or set a direction and have a team actually stick to it." Carmack subscribes to the philosophy that small, incremental steps are the fastest route to meaningful and disruptive innovation. He compares this approach to the "magic of gradient descent" where small steps using local information result in the best outcomes. According to Carmack, this principle is proven by his own experience, and he has observed this in many of the smartest people in the world. He states, "Little tiny steps using local information winds up leading to all the best answers." Armadillo Aerospace Around 2000, Carmack became interested in rocketry, a hobby of his youth. Reviewing how much money he was spending on customizing Ferraris, he began by giving financial support to a few local amateur engineers. Carmack funded the company, called Armadillo Aerospace, out of his own pocket, for "something north of a million dollars a year." The company of hobbyists made steady progress toward their goals of suborbital space flight and eventual orbital vehicles. In October 2008, Armadillo Aerospace competed in a NASA contest known as the Lunar Lander Challenge, winning first place in the Level 1 competition along with $350,000. In September 2009, they completed Level 2 and were awarded $500,000. The company went into "hibernation mode" in 2013. According to Carmack, the work in the Aerospace industry is "simple" compared to
