Telling someone about your love for horses isn't nearly as effective as "showing". That is, be a story teller and write about something more specific. Don't summarize it.
Example: For one, communicating with 1,000 pound animals demands perseverance. Now write about the time when you were preseverative. Why was that important?
I have been kicked, bitten, and thrown out of the saddle more times than I would like to admit, but I am relentless. What were you relentless about? What happened?
I may not be successful on the first few attempts but I will push myself until I am. Attempts at what? What did you accomplish?
