I have a goal of what I want to accomplish by certain times, but I don't have a plan of how to exactly get there.
It depends if I have a show goal. If I do, that's going to be my goal and I'll train all the week / month depending on that show. If I don't, I try to ride once just to see what's our problems (my position, my hands, my legs, her balance, ...) and I'll try to improve our difficulties :)
I like to make weekly and monthly goals with my horses. That then helps me plan our training :)
