 ### Fast Feedback
 
-Getting feedback fast is essential for an engineer. The two great ways of
-getting feedback fast are test-driven development and debugging techniques. When
-you come to a new project, first of all learn how to run existing and write new
-tests and also learn how can you debug things the fastest way (can be a real
-debugger, or just "console.log()").
+Fast feedback is essential for making progress and avoiding wasted effort. It
+helps engineers quickly test ideas, catch mistakes early, and stay in the flow.
+Useful ways to get fast feedback include test-driven development, fast-running
+test suites, effective debugging tools, and simply asking a colleague for quick
+advice. When starting on a new project, one of the first things to learn is how
+to run the existing tests, write new ones, and figure out the quickest way to
+debug. Investing in faster tools, clearer error messages, and smoother processes
+pays off – the shorter the feedback loop, the more confidently and efficiently
+you can work.
