These are the questions you need to ask yourself
1) can i afford to do this
2) Am i doing this for fun or profit
3) What are my expectations

If you answer yes to the first question and fun for the second...go for it...if you didn't i would think twice....it has been stated many times that 90% of owners don't make money....from what heared last time on average each horse registerd in Australia wins $10000 a year prixe money and from my understanding it costs more than $20000 to train....just so you know...
