<!-- They describe effective developer experience in terms of three elements: feedback loops, flow state, and cognitive load. We can only find out whether we are on the right path by getting rapid feedback. The longer the delay between that blue dot moving on my phone-map, the longer I walk in the wrong direction before realizing my mistake. If our feedback is rapid, we can remain in the second element, a flow state, where we can smoothly and rapidly get things done, improving our products and our motivation. Flow also depends on our ability to understand what we need to do, which means we must be wary of being overwhelmed by cognitive load, whether it comes in the form of poorly structured code, flaky tests, or interruptions that break our flow. -->
