I'm a litlle shy too and what I use to do in slow days is to forget about tips and propose myself to just have fun, so I put some music and I sing or dance, I get silly on cam to make myself laught just like nobody's watching and it's okay. Many times, when I do this, people engage in disscusion or jokes.
Another thing that help me sometimes is to imagine that I have a full room of people and to ask myself how I want/feel to be in front of them and what I will do if I had many tippers in the room; and I'm doing that things anyway.
But what helps me the most is that even if before camming I set an ammount of tokens that I want to make...after I log in, I forget about the tips, assume that maybe i'll do zero tk and it's fine and I just concentrate to the people who are in my room & I have fun with myself, enjoying whatever I'm doing. i think that being relaxed and enjoy yourself it's the key.
