Avoiding 'gift horse' syndrome

As elated as I am to have early winners on a card, I am also a bit intimidated.  A good hit early, is supposed to mean that one can't lose for the day. However, with extra money in my pocket, it's difficult not to spread on races where i don't have an opinion. So I TRY to slow to a stop. 

Case in point, at Keeneland, today.  I crushed the first race triple and super and was riding a second race pick-three.  With a minute to go, stewards scratched my move horse--the only contending speed to compete with the odds-on entry.  Of course, you know the rest.  Speed dies, my second pick-three contender loses at the wire.  

Peel off $50 for the rest of the card.  Wallet in pocket. They are not getting me today.
