A poem about insisting on doing one thing.

Continuous achievements, dropping out of school, and previous efforts were all in vain. Gou Zi said "you have to learn", which means you have to learn. Learning is expensive. "Fishing for three days and drying the net for two days" is impossible to make great progress in school. I am most afraid of dropping out of school. As long as I have perseverance and strength, I am not afraid of hardships, I stick to my goal, and I believe I will succeed. ?
