An English poem about school life

Always have a dream and forget those cloudy days. But don't forget your time in the sun. Forget those times when you were defeated. But don't forget the victory you won. Forget what happened to you. But don't forget when your luck turns. Think about your lonely days. But don't forget the friendly smile you have seen. Forget about those plans that don't seem to be very successful. But don't forget to always have a dream. Forget the days when you were frustrated, but don't forget the good times. Forget your failures again and again, but don't forget your victories. Forget your misfortune, but don't forget your luck. Forget your lonely days, but don't forget the friendly smile you got. Forget your bad plans, but don't give up your dreams.
