I will share one that I know I will probably get some flack for.
Something that really gets on my nerves is when someone asks a question about their horse and then they get 15 replies, "You need lessons," "Get a trainer," "Get an experienced horse person to help you," blah blah.
Well you know if that that was an option don't you think they would all ready be doing that!!! Also what is wrong with self taught? There is a lot of people who never take a lesson a day in their life and are excellent horse people. Do they go through some trail an error, sure, but in the end it is teaching you just as much when you get it wrong and then right. Lessons are really expensive and its unrealistic to expect that everyone has the resources to afford them or for those of us who live rurally that there is even a place to take lessons. And if you don't do lessons and are self taught that is just fine it doesn't make you a bad horse owner. As for people who do take lessons that is great too! I think both the trainer route and the do it your self route should be respected. I just don't think the answer to every question is "Get a Trainer."
