First of all, self-discipline can help girls form good living habits, have healthy physical fitness and enjoy all the beautiful things in this world. Some people say that self-discipline is difficult, but I think that everything in this world needs you to pay. You can start with the simplest things, and you don't need to regard self-discipline as a very advanced thing. In fact, you can insist on drinking eight glasses of water every day, going to bed early and getting up early, exercising every day, reading books and reading news every day and learning new things. Only in this way can we ensure that we have a healthy body, and then we will not be eliminated by this society. Although indulgence can bring you temporary happiness, you should believe that self-discipline can bring you lifelong happiness, which is far from comparable.
Secondly, self-discipline can broaden your horizons and make you win the respect of others in your life and live your life with dignity. I believe that only self-disciplined people can understand this feeling. Therefore, as a girl, if you can be strict with yourself, your life will be wonderful and worthwhile. Because of self-discipline, you will demand perfection in everything in your life and refuse to waste time. In the end, you will find that what you get will be beyond your imagination, which will be the basis of your good life.
