Learn the basics of French pronunciation and grammar, as well as a wide range of conversational topics to add to your vocabulary.  Each chapter builds on the previous one to help repeat previously learned topics and develop a better grasp on the language. 

Just like hobby or study you take on, the key is regular practice.  Aim to spend at least 30 minutes a day, 5 days a week, practicing your French.  Before you know it, you'll be a confident French speaker!
