If you aren't familiar with the concept of "Flow", I highly recommend reading the book Flow (also honorable mention for the book Deep Work)
Per Wikipedia: "In positive psychology, flow, also known colloquially as being in the zone, is the mental state of operation in which a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity."
It's essentially the holy grail for productivity,
Per a tweet I can't find the source to: "When we disable ego, we enable learning. Learning is an innate capacity but judgment, fear, and ego get in the way. Pace and quality of learning accelerate with relaxed concentration - flow. There’s even a Japanese word called Mushin (無心). Advanced martial artists enter a Mushin state during combat. Guided by the subconscious, the sword and the warrior become one in the same."
With that being said, there is numerous techniques to help find your "Flow"
If you've personally figured out how you can consistently find your Flow, I'd love to hear how.
