Bankroll

[miraja2]

It doesn't seem like you have a lot of confidence at this point, so I would say start small.
Make your early mistakes with $2 win bets.
Then after you get a little better....increase the amount you bet.
Then, when you lose those races, just start shouting things like, "I handicapped it absolutely perfectly.....but then the horses screwed it up."
Then you're in.
