Release a lot of pressure and start talking about anything without needing to make yourself like someone else. You are given the right to freedom of opinion but keep it in an on-topic context and do not violate existing rules. What's more, you don't need to be shy about one or two high-reputation users even if they seem scary to you. Don't just agree and agree with many other people's opinions, but develop your ability to argue as long as it is correct regardless of who you are talking to.
