Many people value their time more than anything else in the world. 　　Once time is gone it can never be replaced.　 　　This makes time more valuable than money. 　　Time is precious. 　　Nobody can afford to waste time. 　　Once time has gone by, it will never return. 　　You can never turn the clock back. 　　Time passes very quickly. 　　People say time flies. 　　Time and tide wait for no man. 　　We should, therefore, make the best use of our time. 　　If you can manage your time well, you will have a successful life. 　　Try using all your spare time to practice English crazily. 　　Even a few minutes practice while waiting for the bus can be valuable learning time.
