Change is difficult for some, more difficult for others.
In an organization, the individuals resistance or willingness to change is many times proportional to that individuals comfort level in themselves. As team members get older and set in their way, comfortable in "the way they have always done it" many times this blocks them from opening their minds to the possible of what better may come. You even see this in churches, as people sit in the same seat over and over again, and don't you dare try and sit in it one sunday morning.
People are creatures of habit.. but do they have to be?
As I have gotten older many changes have happened in my life, some by my choosing, others not. I have reacted poorly to some and better to others, but through all of them I've worked hard to answer the question " So , what can you learn from this?" Many times it took someone other than myself to help me see the learning needed. What I found out many times stung a bit, applying a magnifying glass to the areas of "me" that I thought I hid pretty well.
The core learning for me was to embrace change.
Learning to see any change as an opportunity to grow, to learn, to make a difference, to become a better me, takes effort. Natural reaction for me (and most) was to sulk, or to harbor bad feelings, but those actions only ever caused me to live in the past and never see what was next. Seeing change, good or bad, as an opportunity is freeing and empowering. It is the open window when the door shuts. Embracing change is a mindset that takes effort and practice.
I am guessing the blue haired woman on the pew left of the isle has not practiced much.
