I don't like sitting by the computer, so I usually go on a sofa or somewhere comfy and just stare at the wall until I come up with what exactly I need to program. Sometimes I use pen and paper, or more recently reMarkable. Then I get on the computer and sprint through the implementation and all tests etc. I cannot do that when working in the office - people think I am lazy and don't work. I hate that you are forced to sit by the stupid machine. Since I won't code anything until I know exactly what to do, I tend to just browse stuff on auto-pilot not event thinking what I am looking at the screen. That as well make coworkers think I am lazy. I feel anxious when I think that I may be required to be coming back. I'll definitely quit if they start pushing hard.
