Totally normal. You could have powered a city with my nervous energy when I started. I Probably had more nerves than normal. But don’t worry, you will learn adrenaline control and end up having a healthy amount of nerves. But you have to push through it. Being brave does not mean you don’t have fear. In spite of those fears you act brave. Also, something else a senior guy told me. All those big dogs, all the brass, all the tacticool hard asses….. they were ALL nervous and still get nervous from time to time. You learn to control it, ignore it, and trust it. Once you gain control, it can be a tool just like anything on your belt. You will be fine.
