Feedback loops are an inherent part of human nature. Homeostasis is just one example — when we are hot, we sweat to cool down. When we are cold, we shiver to heat up.
However, feedback loops really shine when we set up an environment that forces us to change our actions based on our results.
The reason why this works is because of iteration, which allows us to change course when necessary. When you have a tight feedback loop that gives you information to change quickly, you’ll improve much more efficiently.
Imagine two people who want to learn the piano. The first person takes one class each week while the second person takes three classes per week. Both people spend the same amount of time practicing. Who improves more?
Holding all else constant, the second person would learn faster because he created a faster feedback loop. He can self-correct faster by getting more input from a teacher.
There are different ways to create feedback loops. Some can be as simple as:
Finding ways to tighten these loops is crucial to improving anything you do at a faster rate.
