"Because when that coin is in the air, you suddenly know what you're hoping for."
Sounds waay too easy. The one you are hoping for depends not on what is the best decision but rather in you.
And for many I'd imagine that the one they are hoping for happen to be the decision that has the best short-term benefits.
Most hard decisions are hard because of uncertainties and those don't become clear because of a coin flip. And even if you find yourself hoping for something doesn't mean that that is the right thing to do but just as much as what else you want to escape.
Making the right decision is often hard, hoping isn't.
