First of all, regarding the goal, you should set yourself a clear and definite goal. This goal can help you find some fun in your spare time in college, and also improve your knowledge system so that you are not blind. On the matter of making yourself full of fighting spirit in college, my suggestion is to set a goal for yourself every semester, don't be blind and don't follow the crowd. This goal should also be based on your own actual situation. I hope you don't aim too high. And these goals should also be based on the fact that you can guarantee that you can pass or be excellent in all subjects. After all, in college, your main job is study, followed by some sideline businesses.
Secondly, we should have our own standards for our peers. Because good people can inspire your fighting spirit in your study and make you do better in some aspects, while bad people and environment will only destroy your plan, make you worse and make you lose your fighting spirit, so you should choose good people and environment so as to really change your life and inspire your fighting spirit.
Also, if your mind is firm enough, then you can choose to be a loner. If your fighting spirit and enthusiasm can't be erased by time and loneliness, this is the best. Although you will feel lonely in this process, as long as you can overcome loneliness, you will be able to inspire your fighting spirit and succeed in college.
