Learn Portuguese like you learn to ride a bike!
Learning to ride a bicycle is one of the most memorable things in one’s life. Why? It meant freedom and a sense of accomplishment. It was a fun, enjoyable, even an exhilarating experience. Never would one describe it as a boring affair.
Learning a new language should have the same characteristics. Never dull, never tedious. One should look forward to it. If the teachings techniques don’t fit these criteria, I won’t use them!
