Envy italki friends

When I'm reading notebooks on italki, I feel insecure. It seems most of the notebook writers study and learn foreign language much faster than me. Also, they can ask some of questions in their interesting language of interest and they get the answers in that same language. Probably they are able to understand the answers. When can I ask a question in German? When can I understand the answers fully?
I wish I had the ability to learn foreign language fast.

(NOTE: Insecure means you feel like you are inferior to others or that you are not confident about yourself)

Keep practicing everyday, there's no other way to learn faster than that. Good luck and I hope you can speak in German soon! :)
