Writing Goal

I've noticed that in the Camp Thank You Letter Marian and I wrote, for each sentence we started with a noun. Really? I'm a bit disappointed in myself, since I know I could do better than that. Now I know how big of a difference there is when I use different sentence starters, since when I look on my newer pieces of writing, I see that most of my sentences start with all different types, and there's a HUGE difference. Firstly, I'll show you my Camp Thank You Letter, and below that, there will be a newer piece of writing.
