关于热情和实践。 About enthusiasm and practise. (Very short text)

上个月我在中文的学习上没有进步。我没有做很多训练，导致我的学习效果不是很好，我的热情程度也不够，对此我很生气。但不管有没有热情我都要做练习。中文是很有趣，美丽的语言。我不能放弃。

Last month I had no progress in Chinese. I had not a lot of practise, therefore my results were not good, my enthusiasm was also poor.
I’m angry about that. But it shows me that I have to practise regardless of enthusiasm. (In Chinese text I wrote "have not have enthusiasm", I just don't know how to say it correctly)
Chinese language is very interesting and beautiful language. I don't want to give up. (Is there a way to say "Too... to..." as "Chinese is too interesting to give up"?)

Thank everyone in advance for corrections and help!
