I can’t tell for everyone, however what I confidently know is what I should do. The very first task is fall on the floor and try to do some sports for about 20 minutes, next do you best to a short checklist of the tasks you have to complete. Then make a cup of tea, get to your working place and the last, as well as the most difficult and important point is closing the YouTube tab and Instagram app also. Get involved into your checklist for 4 hours, but don’t break any of the points, I have mentioned above, otherwise start all the algorithm again from very beginning.
To cut the long story short, if you aren’t able to complete your work, you will become a strongman or die of hunger.
