Sensitive or thick skinned?

Have you heard somebody scolding  saying "you are shameless and thick skinned"? Yes, I think we do. In our Indian society, sensitivity is considered as a good quality and treated as a complement and thick skinned -  a negative trait. Do you buy that hypothesis? As far as I am concerned, I have started believing the other way round. For me sensitivity is a bad quality and being thick skinned is the winner..
Now that I have passed on my opinion, let me try to prove it. Sensitive people often get offended by a number of things.. When around sensitive people you need to watch out on what you are saying. In other words you become extremely cautious. This build up stress. They take it to their heart all the time and keep thinking about it. And often the person who told such "insensitive" things, feels bad. This bad feeling can often lead to stress and loss of productive working hours. It may lead to loosing friends at times and the overall effect could be enormous. So, in this regard, is it easier to be thick skinned or be sensitive? We hear the word "cool" a lot these days. Coolness is equal to someone who takes it easy. Now thick skinned people also take it easy so, to my understanding now, the cool people are thick skinned.  I would rather like to be surrounded by cool - thick skinned people than by "warm sensitive" people.
In my own personal day to day living, I have realized that thinking about what other person thinks about me is a big dagger. For example, I get upset when loved ones get upset with me. So, I try my best not to upset them. In that process, I go to great length and put myself in trouble - but nevertheless want to please the person around me. According to me this is not a positive quality. I have realized, it is very hard to please others.No matter how much you do to please people, at the drop of a hat, they get displeased and all your efforts goes down in vein..So, why did you try so hard(to please) in the first place? Being assertive and true to yourself is the best thing you can do for yourself!! This reduces the baggage of feigning and un-necessary attempts in pleasing others. So, to conclude I think we should live life without baggage and without thinking what the other person will think about me. Do whatever feels right to you and stay thick skinned always - in other words be cool.......
