Hmmm maybe not really?! It rhymes though and why not? You have come a long way and it is beginning to pay! Your understanding of English should be noticably easier and easier. For many by having a intermediate level of conversation is possible. But this is VERY personal. Some people really don't dare to speak until they feel more comfortable which comes with increased vocabulary. No matter, just continue on. Never despair, there is an end to this method, and by the time you get there EVERYONE will be speaking! (And MOST of you way before the end)
