Freaking out (AA)

So I was listening to a few coaching calls where the message across is ask a 100 people to pay for your services and at least 1 will say yes. So I said why not. Last night I went to my list of followers and did that. About 25 people are very interested for a future date. Yay I have leads! And one person wants to book and we are finalizing that today. So why am I freaking out, nervous and scared? This is not my first client at all. Although it is the first time Injust go to a bunch of people and tell them hire me. These are my prices. Please help me understand my brain.

Thank you!
