One of the writing prompts that I really liked was the one about an emotion that we've had. I wrote about happiness, and the time that I climbed a cliff that had the most amazing view from the top. I enjoyed writing about this because it brought back some of the great memories and emotions from that trip and that specific climb. I found it amazing that nobody will ever have the exact same view from that climb as I did during that climb. I felt successful, because I had experienced something in a way that nobody else will ever experience the same way.
A way that I would develop it into a longer piece is by writing more about my emotions during each part of the climb and describing the view from the top. I only had a brief amount of time to write about each part, so I couldn't describe every way detail about the experience.
