Habits are routine, grooved behaviors based on what-we-know. What-we-know is always based on the past.
Habits are a two-edged sword. Habits help us understand the world quickly. What-we-know creates patterns we can use to solve problems efficiently using a minimum of brain power.
Habits can prevent us from clearly seeing the present. What-we-know may not be accurate or lead us to mistake reality as a previous pattern (with a mistake).
Habits are part of who we are and resistant to change, because they are based on what-we-know. Habits are more powerful than reality, because reality is always new. Knowing prevents learning.
