1) Research what skills I'll need to develop. At my current stage of learning I don't know what I don't know.
2) Figure out a path to start developing skills. This might be writing a small story every single day while also reading books/guides on how to develop as a writer. I'm still writing daily.
3) As I'm becoming mor comfortable writing anything I now need to develop skills on writing specific things. How do I flesh out a character, how do I describe settings, etc. I'm still writing daily.
4) Once I've figured out individual building blocks I'd then teach myself how to construct them together. What elements do stories contain? How do I flow between small sections to weave a larger tale? I'm still writing daily.
I'm sure as I become a more knowledgeable and skilled writer I'd identify other areas I need to work on, skills to develop, etc. It all comes down to identify small blocks and build from there.
