What is a tough decision?

I had never really analyzed the workings of tough decisions in my life, and I have had to make several. Who doesn't? Tough decisions are tough, because one has to let go of some things which one doesn't want to, but at the same time, is not a 100% sure about the consequences of the alternative. The heart goes out to one scenario and the mind says otherwise. One has to live with the decisions made, and only later does one realize whether that decision was right or wrong. 

If it does turn out that the decision was right, one is happy and credits oneself for the success. However, if the decision does turn out to be wrong, there is nothing but only great disappointment. Can one ever know? Is the pragmatic decision, which the mind says, to be chosen or the emotional one, which the heart says, is to be chosen. The only solace to be found in a pragmatic decision is the certainty of avoiding any uncertainties. And in an emotional one, the solace is to be found in the acceptance and the readiness to face any uncertainties. In either case, the decision is not easy and involves an immense amount of reflection and emotional upheaval. Being pragmatic is not easy and even in this approach, emotions are involved.

Neither style is right or wrong. It's just a matter of which one works best for someone based on how that person has evolved through the years. For some, being pragmatic has helped and for some, being emotional has been the way to go. These two approaches will always be at loggerheads and a compromise of these two, seems improbable.
