So, I'm not asking for any sort of money on this game but I have a goal of getting $500k before December the first and I was wondering how do other people make their money on this game.

I know you make money by breeding, selling and showing and I've been doing that and i get highly any money for it.

I just want to see what sort of different ways i can create my own money with other people tips and tricks on how they create money for themselves. :)

If you aren't making good profits from showing, you aren't doing it right. Having a ton of geldings, especially those of higher levels, and knowing when to enter them is the combination that will earn you good money.
