This one goes together with my Tip#1 (don’t be afraid of making mistakes).
TIP 9: Practice The Speaking
How did you learn to ride a bike? Did you learn to do it while actually riding the bike, or did you learn to do it while watching people doing it?
You can apply the same to learning a language: you cannot learn to speak Italian only by knowing its grammar. You have to overcome the fear of making mistakes and try and speak. The moment you will listen to your own voice speaking Italian you will become more aware of the vocabulary, grammar and pronunciaton, and this will boost your confidence!
