At the entrance to Appolo’s temple at Delphi in Greece is an inscription written: “Know Thyself.”

Knowing your brain is to know thyself.

Awareness of your brain’s functions, particularly why your brain is biased for habits is the first step to changing your habits.

Understanding why your brain forms habits will help you find ways to work with it, and not against it.

Let’s start with 3 reasons why your brain forms habit. This will pave way for the subsequent lessons.

1 — To conserve energy and time

Habits make your routines automatic. This way your brain conserves energy and time.

An efficient brain requires less room.

Think of it like taking stairs vs using a lift.

Stairs are more effortful. Your brain will avoid such strenuous tasks like plaque.

If your brain was to engage your energy and time as it performs tasks, you would drop down dead.
