Do আপনি think আপনি can improve অথবা do আপনি think আপনি are already a great writer?

I know that I'm a great writer-but even great writers need to learn and improve in many things. We are all not that perfect.

well I know my self ,I'm not a great writer ,I'm ok ,but yea I think I can improve that I'm a great writer in the future

There is always room for improvement and I am not a great writer, I can still improve.

there's always room for improvement

Yup...my লেখা seems to lack detail. At least to me it does.

Everyone always has room to improve- no one's ever perfect. Not even the world-famous authors. What? It's the truth.
