As the proverb says,“No one knows the value of health until he loses it.”In other words, nothing is more valuable than health.
　　It is clear that health is the foundation(基础) of one's future success. If you become sick, it is scarcely possible to pursue(从事) your career effectively, much less make your dreams come true. On the other hand, if you are strong, you can go all out to overcome the obstacles(障碍) that lie ahead of you.
　　Health is the resource of our energy. What should we do to maintain(保持) our health? First we should exercise every day to strengthen our muscles. Second, we might as well keep good hours. If we get up early, we can breathe fresh air and see the sunrise. This habit can do wonders for our outlook on life. Third, there is a proverb that says,“Prevention is better than cure.”If you pay close attention to your health, you can avoid getting sick, or at least cure yourself of a disease while it is still in its beginning stage.
　　In conclusion, health is more important than wealth. Those who are rich but poor in health are no more fortunate than those who are poor, and healthy in body. If you want your wish to come true, health is the most important component(组成部分) of your success.
