Sometimes we have really bad outcomes.
Recently I received this negative tweet on a podcast from one of my subscribers.
"As a professional handicapper, aren't you embarrassed that your top choice in Race #7 finished last?" 
Luckily, I lost my ego about 30 years ago, and calmly answered...
I've owned over 50 horses.
Some earned lots.
But almost all have had their heartbreaks.
It's an inevitable part of the business.
Racing doesn't have binary outcomes like other sports.
Horses get bad trips, break down, get sick and guess what;
They can't talk and tell us how they're feeling.
Some of my own "Horror Stories".
I. My 2-5 favorite in a 200k race.
I asked the trainer to contact one of our vets to inject a filly's knee with Adequan. He called two. Both showed up at different times. There was a lack of communication, and both vets injected the same joint.
Knee blew up and the horse never raced again.
Cost me 20k to keep her alive, I now owned a very expensive pet.
Trainer got fired.
II. The Wrong Partner
Had another good horse(harness) and foolishly made a certain trainer a partner in exchange for partial ownership.
He had a great rep, and at the time was the leading trainer and driver in Delaware.
He knew the colt had a bowed tendon.
I didn't.
He ran the injured horse because he needed money.
Guess what...... he got fired also.
III. Another Trainer Bites the Dust.
Had an expensive claimer who was the favorite.
He just didn't run well one evening.
Trainer scoped him after the race and found out the horse had a fever.
Shouldn't he have known prior?
Went through a lot of trainers.
IV. One More for Fun.
Some early races can have huge purses.
Had a two-year-old in one for 500k, a win nets me 300k.
The gate opened and my horse went right to the front.
What a great business!
Then my check writing machine did something that took a few seconds to process.
He quickly backed through the field and finished second to last.
After the race I asked the jockey what happened.
He said;
Your horse isn't fast.
Ouch!
Chaos can be a handicapper's friend.
This old Thomas Jefferson line still works best.
