I set up a routine where I did the same things every day.
In the mornings, I woke up and wrote out longhand the regular and irregular verb tables for 1.5-2 hours. I managed to get through an entire pad of paper in two weeks. I still believe that writing things out by hand is the best way to memorize things.
While I wrote, I would listen to Michel Thomas’ language learning mp3s (http://www.michelthomas.com/). On the CDs you listen as he teaches French to other English speakers. It’s really helpful to hear other students make mistakes that you can learn from, just like a regular classroom environment. In two weeks I listened to the foundation, advanced and language building courses twice.
I would run for 45-60 minutes in the early afternoon in the French countryside listening to catchy French music. Music is a great way to learn the intonation of a language and train your facial muscles as you sing along.
