One of the top priorities is to set realistic goals. The key word here is realistic. One should evaluate the horse, the commitment he or she has to the sport, the schedule, and the time. Once this kind of evaluation has taken place, only then can one set realistic goals. Goal setting is also about planning ahead.
Flexibility is equally important.
One must be able to adapt to the unknown and be willing to change things depending on the circumstances. Basically, the best strategy is to pay attention to the details. Pay attention first to the horse and listen to what it is telling you. Let the physical condition of the horse and the lessons that you have learned in the past determine the steps in your overall plan. Pay attention to saddle fit, to nutrition, to shoeing, to clothing, to using what works with your horse.
