Accountability Mirror
One day, Goggins change his life. When Goggins looked in the mirror, he felt frustrated with who he saw that day—a kid with few prospects who wouldn’t be able to make it into the Air Force without getting tough with himself and changing his behavior. He resolved to get into the Air Force by improving his reading skills and studying for the test.
To do this, he decided to use the mirror as a device to hold himself accountable and reach his goals. Each night, he wrote his goals for the next day down on Post-it notes and placed them on the mirror. Then, he’d make sure he worked toward his goals each day. Often, this involved giving himself a tough talk about what he needed to do and why. For example, he’d call himself out for being stupid and say he needed to study to fix that. He found this method more motivating than being gentle with himself. This was the beginning of David Goggin’s accountability mirror.
During his senior year, he focused on studying and being in good physical shape. After he failed the Air Force entry test a second time, his mom connected him with a tutor. His tutor taught him to use memorization to learn, and he’d read textbooks and copy them, greatly improving his knowledge of reading and algebra.
