Has this ever happened to you? Aslo HELP!!?

I am looking for a new horse, I currently own a TWH....I was looking for anything BUT a TWH. Then something just clicked in my mind that said " You dumb pup look at how great what is in front of you is" and that was it I was love struck by TWH...again. As for my other question I ride a 12 year old TWH mare that is DEAD BROKE!! I am looking to buy a 2 year old white walker, not broke. I am going to have her broke by a pro. but I never took lessons on TWH so Im not real sure how you ride their gait properly and I really dont want to mess her up, So is there any tips you can give me? I took lessons on Saddlebreds. I ride English and . I have been riding for 10 years and I lessons for 8 years.
