If you do not understand the problem, every action is noise.

Learning goal

Clarify understanding before acting.
List what you know and what you do not know.
Avoid action as a substitute for understanding.

Why it matters

Acting without understanding multiplies rework.
Checking understanding is cheaper than fixing wrong execution.
Unknowns are data; name them.

Key idea

Understanding means clarity about what is really going on. List knowns and unknowns. Do not use activity to avoid the cost of thinking.

Common mistakes

Acting first and thinking later.
Assuming understanding without checking.
Ignoring unknowns.

Today's move

Before your next big action: write 3 things you know for sure and 3 things you do not know yet. Decide one small step to reduce the most important unknown.

Self-check

You can explain the key idea in one sentence.
You have one concrete move to do today.
