There is another piece of good news. As you will see in the coming
chapters, importing 5,000 to 15,000 new words into your brain in 500 to
1,500 hours turns out to be THE major battlefield in language learning,
representing 60 to 80 percent of your total effort. In comparison, other
aspects of language learning – grammar, pronunciation, etc. – are minor
construction sites. If you are motivated and still willing to follow me,
my first prescription would be that you start learning words on a daily
basis, at least five days a week, and that you start now.
