 ## Introduction
 There are so many buzzwords and best practices out there, but let's focus on something more fundamental. What matters is the amount of confusion developers feel going through the code.
 
-Confusion costs time and money. **Confusion is caused by high cognitive load**. It's not a fancy imaginary concept, it can't be misleading - cognitive load is there, and we can feel it.
