If you are having problems focusing then you are probably not interested in what you are doing. If you are curious in what you are doing then you will automatically be drawn to it. You will want to find out more information and dive deeper into what you are working on.
Being curious is a gift of endless energy. You will naturally be inquisitive and ask questions. You will want more information and all of this will make you better.
As long as your curious the learning will never stop. You will go down many rabbit holes that ordinary people wouldn’t go down. You will try many different experiments just to see what happens. There is no failure on experiments and feedback.
