It doesn't matter how or what your ride as much as it matters that you ride and you enjoy it. The principles of good horsemanship are the same no matter what the discipline. Different tack is used for different purposes, so a western saddle and shanked curb bit wouldn't be much good for jumping, nor would an English saddle be terribly useful for roping cows or barrel racing.
I like riding in my dressage saddle best and love the challenge of dressage, but I also really enjoy trail riding in my western saddle. When I am on a green or very hot horse, I like the security of an Aussie saddle. In winter, I almost never use a saddle and love riding bareback. Although I don't have a horse that drives right now, I also really enjoy driving either a single buggy or a team. It's is all fun!
My best advice is learn and love to ride in any way you can.
