In a recent podcast episode by the authors of "Practical Productivity with PyBites," the focus is on the challenges of maintaining deep work productivity in daily routines. Despite initially believing they were productive, the hosts discovered a decline in their deep work output, which led them to explore strategies for getting back on track. They discuss how productivity can subtly wane over time and share tips to boost deep work levels. The episode references several resources, including Cal Newport's book "Deep Work," Paul Graham's "Maker’s Schedule, Manager’s Schedule," and a productivity course designed to enhance focus and effectiveness, particularly for developers.
