My english is poor.

My uncle has commented my english skills again. My english is not so good. I always have grammar and spelling mistakes. I grow up in Hong Kong. I have not a good chance to study English. He told a number of people started to learn English in their 30s. Yes, there are many successful cases, but I believe I know many many failed cases. Moreover, they paid a great amount of cost for learning English. They need to spend most of time on studying. For myself, I am a busy person. I have others tasks. I just can say “I will try my best”.
