There is a huge myth here about right and wrong decisions.
When we come to a fork in the road, sometimes it is one of those old computer adventure game choices. One route leads to fortune, fame, glory and an annoying dwarf, the other route leads to instant death.
You are in a dimly lit cavern. There are exits to the East and West. There is the dead body of an annoying dwarf on the ground.
Go East.
You go east. Suddenly an enormous fire-breathing dragon appears and burns you to a crisp. Your adventure has ended. Do you want to reload?
Some forks in the road are certainly like that. One way is good, one way is bad. It is important to make the right choice because life doesn't allow us a chance to reload and go west, kill annoying dwarf and get all.
But real life is rarely as simplistic as a computer game. In many instances we come to a fork in the road and it does not matter which direction we take. It's the philosophical idea of Buridan's donkey. A donkey is placed exactly in the middle of two buckets or water or stacks of hay. He can't decide which is closer so he dies of thirst/ hunger/ a logical paradox.
My wife asks me what I want to eat for supper - chicken or fish?
I reply that it does not matter. She has been to the shops and bought chicken and fish. Therefore I am going to eat chicken and fish in the near future. Whichever one I choose for supper tonight, I will have the other one tomorrow night. She is asking me to be Buridan's donkey.
"Yeah, yeah, yeah," she says. "We've had this discussion before, smart-ass. What should I cook tonight?"
Sometimes when we get stuck at a fork in the road, we don't know which direction to take because it doesn't matter or because the decision is so finely balanced.
So when we come to a fork in the road, the first thing we should ask is "how critical is this decision?" If the decision is not critical, then flip a coin like InspectorFarquar suggested. It really doesn't matter what you choose. Chicken or fish? The left hand pile of hay or the one on the right? Who cares? Just pick one.
If the decision is critical and you still can't make it then perhaps you don't have enough information to make the decision. If you have time, go get some more information.
If you have got as much information as you can and you still can't decide, then pick one at random again. If they are that close they are probably as good as each other.
In this instance, I suspect that you are in a Buridan's ass situation. You can probably make either choice work. There is no right or wrong. So stop staring at the choice and just pick one. Doing nothing is almost certainly worse than making a wrong decision. Then having made your decision, forget about it and focus on making your decision work. No looking back.
