Indecisive; defined as a situation where a particular person could not make a decision over a matters. Factors that may cause the person to be indecisive may be things like self-confidence, self-ability, etc. (wIX. 1989. p.1989)

In a certain situation where you may have predicted the best and the worst outcome for making such vital decisions, how many would actually follow their thinking and how many would have follow their feeling?

For those who would most likely follow their mind, yes, the damage or impact would probably be lessen. But then, there remains a part of your heart that would not be satisfied with the outcome because most of the outcome wouldn't be as nice as imagined. It normally takes miracle for such people to have a happy ending.

For the "feelers", the process resembles a gamble. A situation where the outcome may be a 50:50, they gamble the results with the confidence provided from their heart. The feeling that they are doing the right thing for themselves. The lucky ones would get everything they hoped for while the unlucky ones would get nothing back; they may have just ruin every single hope and opportunity that they've got by taking such decision. Those succeeded would gain the maximum satisfaction with the whole situation.

As the concluding part, be happy and thankful if most of your problems can be solved with the thinking and feeling providing the same answer to it. Being in such a situation does not improve any sorts of critical thinking or creativity. The most that a person can gain is an improved decision making and stress-management. No others included. 

Update @2014: I wonder if I'm making a correct decision, but sometimes I feel defeated by the situation, rather than my own decision. I really cherished a lot of thing that happened, I really hope that it won't just go away just like this. I know I am the one responsible for this, I just didn't know how to get this fixed. What I lost is a lot more than it appears to everyone looking at me.
