You want to reach to native speakers level, so how do you limit the words you`ve got to learn??
Its better to read a lot of short stories, and to have a general knowledge to be capable to discus anyone about any thing (Fluent).
Practice a lot thats most important thing.
As you said. you want to be fluent so do your best to achieve that, (don't limit yourself).
but at least I think 10 words per day will be fine at beginning
Wish you the best
