Ho do you focus at work?

I was able to focus on my academics by forcing myself constantly for days and hours and minutes just before the exam and suddenly my hyperfocus would kick in on the last day of the exam or so after immense pressure and I was able to study for a day or mostly half a day and get through the exam. I have found this impossible to do in an office environment. It’s as if there is an exam everyday because everyday I need to complete certain tasks. I am unable to push myself so much as I do in exams and have never managed to get the focus. Thus, I have been fired in every job. Eg. for my masters, I forced myself something like 15-20 times to sit on my desk and start my work. I was able to somewhere on my 15th or 18th try. But it’s impossible to replicate this is an office environment. Because I would have to do it every single day to get my tasks done. So how is everyone managing to keep their corporate jobs?
