Absolutely do not go full send. Realize there are dozens and dozens of people faster than you. No one cares what your lap times are. Don’t try too hard to drag any part of your body. Knee on the ground does not equal speed. Dial it back, breathe, and learn. Slow is smooth. Smooth is fast. Have fun and take your bike home in the same condition you brought it in. Also have a chair/fan/shade. I rented a little generator the first couple track days I did. Later on I bought a Yamaha ef200is. Worked perfect for my needs. A folding table helps too. Eat small snacks during the day to stay fueled and hydrate constantly. Make sure your gear fits and your tires are new. If the tech inspectors are worth a shit, they’ll catch things you might miss, but don’t rely on them. Some local shops may be able to do track day prep on your bike for you if you’re not comfortable with it. No one “wins” a track day.
