Since my Dad is the reason I have A.D.D I asked him how to stay focused. Number 3 is a favorite
1: Discipline. You just make the list and execute it using pomodoro so your lock with the task is not broken.
2: Exercise. Its all just chemicals. Your brain doesn’t work with toxins pumping through it. It needs oxygenated blood. If you need to watch a 40 minute video on how to do something, watch it on an elliptical. You wont get bored and youll take in the information properly.
3: Bum glue.
