I am sorry, but I don't see how that is relevant to this poster. There is nothing wrong with asking questions. The OP is just asking incredibly general questions that could be answered with some involvement in the discipline, which when people suggest this, she claims to have. Thing aren't adding up.
If things were more specific, people would be able to provide her with more targeted and helpful advice. But until she is more familiar with the discipline, which really comes from being actively involved, she isn't going to find much help here.
Agreed. OP - what MIGHT help (and agreeing with GoAppendix that no internet forum can take the place of, nor should it take the place of a trainer) is if you posted a few videos. Then maybe people can help at least point out any huge errors you may be making, which could save you from going really backwards. They also might be able to tell you if your horse is even capable of being competetive in that realm. At least then you would know if this is something you might want to persue. Have you looked for AQHA trainers in your area? I know they can be hard to find. I haul an hour one way for mine.

Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
