Habits are routines that occur automatically without conscious thought and are formed through repetition over time to free up the brain's resources. Habits are initially formed consciously but then become unconscious. To break a bad habit, you cannot eliminate it but must replace it by finding the trigger, eliminating that trigger, and substituting a new habit and reward. Successful people form habits like waking up early, exercising regularly, planning their day, prioritizing tasks, and practicing deliberately and hard work.
