I tried that. The deal was she could work for her lessons. She was a nice kid so I'd let her trail ride with her friend whose horse I boarded. My mistake. She became less interested in working. I switched the plan. I'd pay her for her work, and she could spend her money however she chose but would have to pay for lessons or riding time. That I found that worked out far better. If she bummed around with her friend and did little she was paid accordingly.
