Habits are ways of behaving that become ingrained by repetition. You do something so often that it becomes automatic. With motivation and concentration, you can learn to break bad habits. People are moved to change for a variety of reasons. When it comes to self-improvement, the reason that you change is because you come to care enough about yourself, to make it worthwhile.
Inner values play a role in change.
If people make behavioral changes without changing their internal values, beliefs and attitudes, the new behaviors are less likely to stick. Strong motivation, then, makes change easier. Before you do anything, you must have at least some desire to do it. Preparation is necessary, too. As creatures of habit, we prefer the status quo.
