The Emerging leader program at work had a guest speaker who was there to speak about happiness at work. He said that one must not tag anything as bad, for there is always some learning from it. My take away from that was, Everyone is a genius in retrospect.
There is always a lot of emotions associated with change. I have a substantial change coming up in my way of life right now, looking forward to it, scared sometimes, anxious some other times, excited too. Bur emotion and logic seldom agree, we find our answers and convince ourselves with reasons. Resistance to change is not always from within, its from all around. The moment you announce a new direction, you will have people around you wanting you to pay caution to that direction. Some do it because of genuine concern, so do it for the pure sadistic joy of causing guilt and some do it fearing change in their own environment because of the influence you have. People who enjoy instigating your guilt are the ones you want to kick, but that is a whole different matter.
Letting go any set paradigm is really hard and I firmly believe it has nothing to do with what you are actually getting in return. Getting use to the change always takes its own time and once that is done, it becomes a way of life.
Once you have a good enough motive to make that change, then you are convinced. All other stuff just falls into place. So ultimately its just the idea of change that that one fears or challenges, but never the change itself.
