Begin conversations with everyone you can. This website is a good start. Everyone here is trying to learn a new language or improve on the language(s) they already know. You are already off to a good start. Use this website, and others, to connect with people. Let the conversations go from there. Everything will be fine. You will see. Just give it time and keep talking with people.
Like in everyday life, on the Polyglot Club website, "give first and receive later".
That's to say : help others improve their language skills and other will help you too.
I think this is the best way to have nice conversations and improve your communication skills
