It's weird, I remember the first time I had to do Combat Life Saving was pretty nervous moment for me. I didn't know if I did it right, and I spent the whole time afterward shaking hoping I did everything right. Yet, I still remember shaking pretty badly when I asked my wife to marry me. However, if I had to say the most nerve wrecking time in my life is the first time I met my daughter after a deployment. She was only 6 months when I left, and she was 14 months when I came back, the whole trip back I was very unsure if she would remember me. I lived on a little fob during that whole time, so she only heard my voice when I called. It was a great relief to hear her say, 'daddy' and point at a phone :).
