Longtime listener, first time caller

[JAdams]

We all had starts like you. Hang in there.

I would suggest that you work on two things. First, see it and call it. Get to the point where you are comfortable seeing a volation or foul and immediately hitting your whistle. It will be automatic from then on. Second, keep studying the rules to get better. If you see a play and aren't sure you called it correctly, look it up when you get home. Then you'll know for sure the next time.
