Angelina quickly improved speaking-- when she stopped studying grammar. This is your second rule.
Stop studying grammar.
Right now. Stop. Put away your grammar books and textbooks. Grammar rules teach you to think about English, you want to speak automatically-- without thinking!
With Effortless English, you learn English without grammar study. Your speaking improves quickly. You succeed. You speak English naturally.
So Rule 2 is: Don't Study Grammar!
