　　[寫作導(dǎo)航]習(xí)慣不論好壞都是后天形成的，一旦形成，就很難改變；好習(xí)慣是祝福，許多成功人士都承認(rèn)守時(shí)、早起、誠實(shí)和毅力等是早期形成的；壞習(xí)慣如粗魯、懶惰、說謊、偷盜和誹謗等惡習(xí)是我們應(yīng)努力避免的。

　　Habits， whether good or bad， are generally acquired。 When a person does a certain thing once and again， he is impelled by some unseen force to do the same thing repeatedly; thus a habit is formed。 Once a habit is formed， it is difficult， and sometimes impossible， to shake it off。 It is therefore very important that we should take great care in the formation of habits。 Some bad habits formed in childhood may remain lifetime。 Older persons also form bad habits， and in some cases they are ruined by these bad habits。

　　There are good habits which， when formed in early life， are great blessings。 Many successful people declare that they owe much of their success and prosperity to the formation of such good habits as punctuality， honesty， and perseverance in early life。

　　Such habits as rudeness， laziness， stealing and slandering are bad habits。 If we want to be useful to society， we ought to keep away from ail these vices， and strive to acquire those habits that are proven to be good for ourselves and others。
