Importance of Feedback

It is a common knowledge that the only way how to improve and get better is to measure the results in the process.

How Peter Drucker said: “If you can’t measure it, you can’t improve it.”

Let’s add another related quote from Elon Musk:

I think it’s very important to have a feedback loop, where you’re constantly thinking about what you’ve done and how you could be doing it better. I think that’s the single best piece of advice: Constantly think about how you could be doing things better and questioning yourself.
