You need to get past the pride issue, and make that horse do what you ask. My old guy used to get excited jumping also, and we spent lots of time doing patterns around the jumps at a posting trot, sitting trot, etc...at all times making sure that he was totally listening and "adjustable" (meaning I could speed his gait and slow it when I wanted). WE then also went to doing a few jumps, but not always the ones he would expect. It there were 3 in a row, we might only do 2, first and last with a circle around the middle then go to another he never thought of. Keep them thinking and paying attention. It is very very easy for them to just go into "auto pilot", and at that point, you lose control to some extent. I would suggest you keep in mind who is driving!
Get throughout this and you will be a better rider for it. IF there were no challenges you wouldn't be learning. Pride has nothing to do with it.
