most passionate employees are not those
who followed their passion, but instead
those who have been around long
enough to become good at what they do

jak głęboka praca
uratowała mnie przed
ścieżką menadżerską
Deep Work
Professional activities performed in a
state of distraction-free concentration that
push your cognitive capabilities to their
limit.
These efforts create new value, improve
your skill, and are hard to replicate.
Shallow work
Non-cognitively demanding, logistical-
style tasks, often performed while
distracted.
These efforts tend not to create much new
value in the world and are easy to
replicate.

• Deep Worker: No, I can’t forward
emails because of where I live

______ is a wonderful thing for people whose
role in life is to be on top of things. But not for
me; my role is to be on the bottom of things.
What I do takes long hours of studying and
uninterruptible concentration.

This is Bill.
Bill doesn’t obsess with frameworks.
He learns the underlying concepts. Deeply.
He doesn’t change his framework together with his socks.
