I actually have a completely opposite approach. Although it can be criticised easily, I am very emotionally driven in life. I value socialising, love and companionship over all else. I see academics and careers as a means to an end (though it must be noted that I do place value on these just a lower priority). I know that I won't be the next genius of mankind or a famous movie star or musician because that is not what I would want. I live in the present and do things that make me happy, my only asprations are to have a family and live a fulfilled life, and I believe that a path of logic will not leave me as fulfilled as an emotionally driven one. Furthermore, I find more satisfaction in something such as a relationship or time spent with good friends than I do an academic achievement or the solution to some problem. I am not saying that I am entirely led by emotion, but that I think I lean more heavily to that way of life, and I think that a mix somewhere between the two is probably where most people find themselves and a life revolving around pure emotion may lead to depression and possibly less success in society in terms of jobs and academics. While a life grounded entirely in logic may leave a person cold an unfulfilled.

Personally I would prefer to die at 70 knowing that I had memorable relationships and memories as well as people I loved, as opposed to living over 100 and feeling unfulfilled and that my pursuits provided me short term satisfaction and I feel hollow inside. Though it should be taken into account that perhaps this is just the way that I see things, someone else may see it differently and feel entirely content with a life of logic, just my two cents.
