I'm not the most qualified to answer this but...

- Reduce distractions. Pay attention to the things that break your focus and aggressively mute them.[0]

- Treat yourself like a plant, not a machine. You need the right conditions to grow. This means good sleep, good nutrition, and the right setting. This affects your focus.

- Consider that some approaches might not work for you. Not everyone learns well in a classroom. Explore other ways of achieving your goals. Alternative work arrangements could suit you better.

I can focus uninterruptedly in something for long hours. I don't have the urge to check email and social media that is so common nowadays. Some years ago, I read Deep Work and implemented as much as I could and those have served me really well.

With coffee, I can focus on the hardest things for ~2 hours.

I also mediatate almost every day.

In the last year, I have also fixed my sleep (was messed up for ~9 years)

As to your third point, I am familiar with my own patterns and can get things done. Just long term discipline-requiring tasks seem unachievable.
