As the proverb says，“No one knows the value of health until he losses it.”In other words，nothing is more valuable than health.It is clear that health is the foundation of one s future success.If you become sick，it is nearly impossible to pursue your career effectively，much less make your ideals come true.On the other hand，if you are healthy，you can go all out to overcome the obstacles that lie ahead of you.
Since health is the resource of our energy，what should we do to maintain and enhance our health?First，we should exercise every day to strengthen our muscles.Second，we might as well keep good timetable.If we get up early，we can breathe fresh air and see the sunrise.This habit can do wonders to our health.Third，“Prevention is better than cure.”If we pay close attention to our health，we can avoid getting sick，or at least cure ourselves of a disease while it is still in its early stage.
In conclusion，health is most important.Without good health，we could achieve nothing.If we always keep fit，we have already possessed the key to success.
