Choosing Not to Speak

It can be said that a man who knows what he wants in life has put him self on the road to discovery. I can believe that. Once you know what you want to do in life their should be nothing that stops you from exploring the vast reaches of your new found world. The trouble is (for me at least), what to do when you reach a fork in the road? What happens when traveling down your path you reach a point where you can go one of two ways. And you have no idea which one you think is better? How do you decipher which one is better if both options are viable for you, but not cooperative?
