Confused on what to do

Hello all, I am a 2023 graduate and started my job around 2 months ago in the data science field. Everything is going ok till now but now I want to go deep into the data science field as I am feeling that I am not learning enough. I am currently working in the NLP field, any suggestions on what courses can be done or what topics to explore more from the experienced folks would be helpful. Any course suggestions that can explain from scratch to intermediate or advanced level are welcome (paid or free) Thanks 😊
