Instinctive Diplomat

Today I was having a conversation with a good friend of mine about which is better? Being instinctive or being diplomatic? At times during conversations, words just flow out of my mouth. I mean, If I feel that what I speak is correct, I blurt it out, even if others think that it is crap. And that is how I take most of my decisions. I think about them for a couple of minutes. Think if what I am doing is correct or not? If it appears correct to me, I hardly spare a second thought. Coming back to the issue whether being instinctive serves you right or being a diplomat serves you right? Now let me provide my definition of being diplomatic! Diplomatic to me is, choosing one's word carefully and being cautious. I would agree to the point of being cautious if its some big decision. But for petty conversations amongst friends too, if one chooses to being diplomatic, it kind of does not serve the very purpose of having friends right? Even if you crap out something to friends because of your tendency to react instinctively, your friends should be able to understand you right? In that way being instinctive does help! And how about taking decisions? One should not regret making any decision at any point of time if it is taken on an instinctive manner! My personal belief though is that being a diplomat is what all those UN officials, IAS officers are for...A normal human being can live based on his gut feeling and intuition!
