The race horse doesn’t choose to wear blinkers.
The jockey and trainer make that decision.
Depending on the situation, blinkers can help or hinder.
I’m sure if you’re a jockey, they’re helpful. But if you’re going on a cross-country horse riding trek, they’re more dangerous than helpful.
We all have blinkers in our own lives; knowingly or unknowingly.
What blinkers have you got on today? This week? This year? Since you were born?
