1) learn phonetics and pronunciation
2) learn a base of of the most common words (he has a list of 625 words, I think wikipedias "simple english" word requirements would be another good source). Do this with anki.
3) start studying grammar
4) move onto native materials (while continuing with anki)
I also think that most people massively underrate vocabulary study. With consistency, at only 15 words a day you could deeply learn ~5400 words a year with anki. I think it would be pretty easy to do more if you were dedicated, but 15 is pretty sustainable. The rate you tend to be taught vocabulary in college level courses is crazy low.

I hope this doesn't feel too spammy but I'd love if people had any feedback on the basic idea behind the tool I posted here: https://news.ycombinator.com/reply?id=12717657
