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.

______ 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.

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