1.Healthy lifestyle: eat less junkie-food, exercise, and have a good night sleep (sleeping is the most important for me). Avoid stress as much as you can and try to live happy life instead.

2.Less news: stop watching tv and read less news. These make your brain process less information and reduce the cognitive overloads.

3.Single goal: decide what you want to do or what skill you want to achieve. Do not try to have multi-goal or multi-tasking while you are focusing. In general, you want to have zero distraction so no phone, youtube, music, email.

If you feel tired after 3-4 hours, do something else to relax your brain til you feel ready for the next session. Do not take it too serious and enjoy the process instead. It's getting better everytime so let it be and just have a good day!.
