> small steps first, letters, then words, then sentences, then ideas. And finally, after mastering reading, one can try writing one's own ideas.

Just a nitpick. You say one should first master reading, then master writing. But I think both go together; I would just reverse the logical order of the two concepts (small steps and reading-then-writing):

- read letters

- write letters

- read words

- write words

- read sentences

- write sentences

- read ideas

- write ideas

Of course, it is not a fixed frame either, but it gives the main idea.
