Health is the foundation of one's future success. This is because health gives us strength and happiness. If you are healthy, you can do whatever you need to do to realize your hopes. On the other hand, if you are sick, it is impossible for you to go on with your work or studies. How can we have good health? Firstly, forming good habits is very important, including getting up and going to bed early. Secondly, doing exercise every day will help to strengthen you not only physically, but also mentally. Thirdly, a proverb says, "Prevention is better than cure." Try your best to keep fit and avoid getting sick, or cure yourself of a disease while it is still at an early stage. In conclusion, nothing is more valuable than health. With good health, you can study and work efficiently, you can achieve more success and make a greater contribution to society.
