I think I know what you mean by this, since its my overall multi-year goal as well. I'm calling it my 'writing journey'. 2015-2017 was mostly NaNoWriMo and note-taking, but that proved to myself I could develop ideas. 2018 I wrote short stories outside of NaNo and proved to myself I can write a semi coherent first draft. 2019 is the next step, polishing and editing stories and improving my handle on the writing craft. 2020 will probably be focused on speeding up the writing process, but we'll see what happens by this time next year.
