Lifeguards

I am training to be a lifeguard tomorrow!!!!

I am a little nervous, but excited too. I’ve looked it up and I’m pretty sure all there is to do is swim about
500(is it meters?), dive to the bottom and pick up a brick, wade in water for 5 mins, and take a test.
I’m sure i will pass that.

I am not nervous about that as much as I am when I think about actually saving a person’s life. The risk in it. I would be privleged to do that but I guess I am doubting myself whether I can save someone.

Can you lifeguards please give me some input?

GOOD LUCK, AND DO NOT GET NERVOUS
