You are an accumulation of your habits. From how you get out of bed, how you shower, how you dress, how you shop for food and eat meals, how you exercise, how you walk, sit, and talk, how you respond to the world, how you act in front of others, and how you think; you are living out your habits.
Habits are necessary. Because they typically come naturally and automatically (“through habit”), they free up your mind so you can concentrate on how to survive day to day. You don’t have to think about how to drive your car so you can be on the lookout for danger while you are driving. You don’t have to think about how to walk so you can concentrate on where you’re going.
