A couple of things to add to your list: Go to bed early - 9-10pm and wake up when your body feels like it for a change. If it’s 4-5 am, you get more hours of dark and focus time and your brain is at peak executive thinking, so you can see the bigger picture and write much wiser code. Fasting for a bit may keep your focus as well for a while. If you wake up and are distracted from hunger, drink a cup of plain while milk or plain yogurt. The protein and fat will be an instant boost to your brain and you will stay focused until you get hungry again. If you keep to meat, dairy, or sugar-free protein and fat you kan keep your focus all day. Carbs will crash you. When you feel tired or unfocused, or ready to go to social media, take a nap instead. You can eat some carbs now as they can help you fall asleep faster. When you wake, apply the same principles. I had to work for my own startup for a while and a squeezed a whole bunch of top quality code out of my brain. Without enough sleep or quality fatty protein, the brain gets distracted more easily or operates only at lower levels of abstraction.
