It's true that everyone makes mistakes. You needn't worry too much.
Take me for example. One day, I spent so much time playing football with my friends that I forgot to do my homework. I said sorry to my teacher and finished it the next day. I found it important to achieve a balance between schoolwork and hobbies.
It doesn't matter whether or not you make mistakes. What matters most is to correct them and learn from them. In this way, others will understand you. Then you will feel much better.
