What should i do?!?!?

what should i do?!?! I want a horse soooooooooooo bad but my grammy says no. she doesn't want a horse. and also she says it is to hard to take care of and all of the supplies are to expencive. so should i just wait untill im older when i move out to get a good job like my step mom pepper. she made $1,800 a month!!! but im lucky to be able to have horse lessons even though it is only once a week in the summer. and plus my friend has 2 horses and she doesn't have much space but i have 2 1/2 acors of land but mostly woods grrrr.
