I concentrate all my efforts on the things I want to accomplish in life.

The hidden word in this one is *all*. Concentrating all your effort on what you want means withdrawing it from something else, and the something else is rarely a vice. It's usually a decent commitment you would rather not disappoint anyone by dropping.

That is why focus is uncomfortable. It isn't a productivity technique so much as a small series of disappointments delivered on purpose.

Write down everything currently drawing on you. Eleven items is normal. Then find the one you could release this month without disaster, and actually release it.
