A habit is like a tree grown crouched. One cannot go to orchard and take hold of a tree grown such and straighten it and say now get straight and make it obey him. When one is young, he can acquire good or bad habits. One starts doing certain acts for the sake of pleasure, for the sake of fun and if one is doing a particular act at regular or irregular intervals, one be starts enjoying it and starts feeling the necessity of doing it again, at that particular time and it gradually takes a form of a habit. Every chain smoker or a habitual drunkard never starts smoking or drinking as a habit. He simply begins with such an act for the sake of company or for the curiosity of taste, or for the sake of fun in the company of his friends or otherwise and he starts smoking or drinking alcohol. Now and then and afterwards, he consumes it often, and gradually it becomes his necessity and then the habit is formed. Habit is cultivated slowly and gradually. Habit is nothing but a slow and gradual intake of something, performance of some act, etc and when it becomes a necessity, it is called a habit. We can observe many people, who have unwarranted habit of utterance, while walking , habit of eye while talking, habit of strange gestures during conversation, using filthy or abusive language in friendly talks and so on. We find people applying their hand at the nose, at the ear, at the chin, or moving fingers or legs while thinking, talking in general. A strange thing about such people is that they are not aware of their actions in the beginning and at a later stage the habit is formed. Some people have good habits of punctuality, accuracy, cleanliness and waking up early in the morning.
