Learning isn’t normally about hustling. But it should be. We do have the power to consume and understand immense levels of information, and we should always be pushing ourselves to learn more. No matter what your career is, your success will likely depend on your knowledge of your field. Growing that knowledge ought to be your highest priority.
If you can repeat important tasks, over and over again, you’re not wasting time doing something you already know how to do. In fact, you’re allowing your brain to recognise the patterns, apply and consume deep learning, and become a part of a bigger and more contextually relevant system.
