Good goal is to not cry or look panicked haha.
Seriously though, take your time, don't take crap from people, don't fall for tip scams (most sites you can see their token counter go up vs just the chat alert that you've gotten a tip), move around, have the cam set up so you can stand and they can't see your face - works sooo well if you're tired of smiling, need to roll your eyes, or need to check something without them noticing. Have water near by and try to have fun! Remember, you're in charge of your room! You can ban and mute anyone you feel you need to and don't feel bad about it.
