Tip 2 for better spoken English - DO NOT study grammar RULES

Tip 2 is DO NOT study grammar rules. I know this may be a surprise to you because your English teachers have always told you that you must study grammar rules. In high schools or secondary schools, in universities, in language schools, the English teachers teach grammar, and then they teach more grammar, and then they teach even more grammar. And that is the method you have used to study English.
