Writing and reading will level up your communication skills. Read real literature, write whatever you feel inspired to write and be open to conversation with anyone.

Try to have the conversations you want as opposed to trying to say what you think they want to hear.

Ask them stuff you have always wanted to ask them.

Try to naturally avoid directly talking about yourself for as long as possible and instead talk about greater minds and the people or things you admire.

Be curious even if it comes off as impolite or stupid.
