'doing something with horses'.
is too big a subject to advise on, does she want to be in racing, breeding, riding school work, training, veterinary based, showing, jumping, eventing, dressage? as a professional rider or a groom?
unless she is very good ( & pretty lucky) she is unlikely to earn a good living from horse work, many of us who went into it for the love of horses found we couldn't even afford to keep our own horse on the naff wages, it ended up as a choice between having a horse & working with horses, later still when marriage & kids entered the frame it gets even more complicated.
having said all that some do manage to have it all......but not many.
i would suggest she uses her week-ends & holidays to get experience at the types of work she is interested in, that way she can narrow down her choice and learn the truth of the industry & not the soap opera sh*t the kids magazines tell them. a good yard will always teach you something, & even a bad place should teach her something too, even if only how not to do something.
i have seen many starry eyed kids waste their time & give up after a few years to go into 'normal' work and have a private horse.
a kid who hated school did week-ends etc for me, i helped her learn and later she went on to her BHSAI & then BHSII levels before becoming disatisfied with long hours, poor wages, terrible work conditions, (living in a caravan & bad employers), & not having her own horse,
so she gave up horse work and retrained as a hospital physiotherapist, it took her a long time as she had to start at GCSE level exams right through to her degree etc, but she now owns her own house, horse, car etc has a good wage and teaches & coaches in the evenings and week-ends, thats her compromise between horses and work.
if your girl is dedicated, none of this will put her off, if she is talented & lucky she will make it, if she is a happy soul who likes mucking about with horses and does not care about anything else, she should be ok.....but she can't say she was not warned.
good luck bye
