The Thinking Behind The Tweet
Your brain reacts when you say things like, "I'm too busy." and "I don't have time." When your brain hears you say things like that it, subconsciously, begins to work to help you out. Your brain knows time is a thing it cannot control. Your brain knows your body is a thing it can control. So, your brain works to control your body by providing it chemical and electrical changes to help it deal with the stress you are telling it you are under by saying things like, "I'm too busy." and "I don't have time."
Self-stressing about time...now there's a destructive habit!
