how do you pay for this lifestyle?

So i’m just curious about like what jobs you have to pay for the “equestrian lifestyle” or how you pay for it. I’m trying to find some good possible things i might want to major in for college, but something that i can live off of with all the expenses of being an equestrian etc. I’m open to really anything to be honest, i was looking into trying to major in being a vet tech or something to that effect but it just doesn’t seem like the yearly salary is good enough to sustain off of, thanks!
