How are you more likely to make an important decision — by reasoning through it, or by going with your gut?
I create pro and con lists, look for advice from friends, family, and the internet and then once I have it all set, if the original decision hasn’t already been made by someone else or by the consequences of earlier decisions then I try to get a feel for what I should do based on everything and make a snap judgement from my emotions. That’s just my way. Facts are very useful, but generally the feeling of doing a thing is far more compelling. Answering the What and How is certainly important, the answer to Why is the topmost consideration. The decisions for Why usually come from instincts and gut-feelings.
Just like everything else, it’s good to do the leg-work and be deliberate but in doing all of that, in the end it’s all in the gut. I have to have faith that doing all the leg-work has set the stage for the drama to play out in my mind and whatever my decision is is the right one for me.
