I liked working with kids in a high-energy environment. I was always on the go and there was little down time, so the days went by quickly.
What I wish was different
I wish that I didn't work so many hours. I was working 9-10 hours a day, 5-6 days a week. By the end of the week, I was exhausted.
Advice
My biggest piece of advice is: if you love children, games, and lots of energy, do the job. If that experience sounds terrible, this isn't the job for you.
