You shouldn't consider getting a horse yet.
You see, owning a horse is not just the privilege of riding whenever you want.
It is also knowing that you may be forced NOT to ride for a very long time, if your horse gets sick or injured, and you most likely won't have any funds left for lessons on other horses due to medical expenses.
It means being there for your horse in illness and pain, in blazing sun and howling winter storms, in the earliest morning hours and the black of the night.
It means sacrificing much of your free time, your social life and other things you might be used to, because caring for your horse will have to be a priority. And it means hard, hard work 24/7.
It means not panicking if and when, God forbid, your horse faces colic, laminitis, injury, fractures, or just being trapped in an unfortunate situation, and knowing exactly what to do - therefore, it calls for extensive knowledge, which simply cannot be gained over a few weeks of lessons at a riding school.
It means knowing and managing your horses diet as an ABC, which is a separate science for itself.
It means a million of other things, miniscule details, that can turn into a tragedy or just a sore horse and an unhappy rider over a split second, if you don't have the much needed experience, which can be gained only over hours, days, months, YEARS of practice.
Besides, you cannot just keep a horse alone on your property - they are herd animals, they need a companion of their own species, therefore - count all the expenses twice, and add some emergency funds as well.
Fencing, psychology, training, tack, health, hooves, feeding... It's a science, it's for a lifetime. Nothing is easier than buying a horse and hoping for lots of nice rides...but, when you get there, you might face a very rocky road. And find yourself there alone.
Be patient, educate yourself, try working at a barn as a working student, try to learn as much as you can, ride as many horses as you can, observe everything you see and never be afraid to ask for an advice. You will definitely be ready for your own horse, if you do so - but only over time. Good luck! :)
I have come a long way, to surrender my shadow to the shadow of my horse.
