Learning modes

While there are many ways to describe the state of memory, we'll use two: focused and diffused mode.

Focused mode is when we intensely use our mental capacity to do a task. — e.g., solving a math problem, completing a coding competition problem set, cooking a new meal, Writing, Illustration, Note-taking.
Diffused mode is the relaxed state of our mind. It often happens when we take a break, walk outside, and give in to guilty pleasures.

Despite the conception our brain is working whenever we focus, our brain is working all day.
