Should the Mind be Dynamic or in a State of Status Quo

This is a question that often comes to mind. People say that our approach to life should be dynamic but what about our core values should they also change with changing times or remain time tested and rooted in our very existence. Our values are part of our very being, our existence. They are something that we acquired since our childhood and they shaped our personalities. So, should these values also be dynamic or should they remain status quo? 

I have gone through many turmoils in my life and my mindset has changed from an angry, emotional person to a calm person who is at peace with life and the people around me. With such a chequered life should I retain my values? I find myself often pondering over this. My mind is both a combination of static and dynamism as I try to retain the values inculcated in me since childhood and try to have a dynamic approach to life. Not being rigid about anything in life, having a flexible approach to people and situations are important aspects of my constantly developing personality. 

I have met all sorts of people in my life, some have left a sour memory in my interaction with them and some have left me with joie de vivre for life and my dreams and ambitions about life. 

I would like to narrate my experience with a former colleague, he had a negative attitude even with the most positive people around him. I had shown him the new version of the hare and tortoise story, where the hare and tortoise work as friends and help each other with their core skills, I said if we have this approach in office work each one of us will benefit. He told me this is good only in a story in office work we have to pull each other down. I was aghast and realized that he would have this approach all his life. He still communicates with me but is not happy with my progress in life.  Thus I who had an emotional connect with this friend realized that all he wanted to do was pull me down.

There have been other friends and colleagues who if not being supportive have not tried to pull me down. Thus life has been a mixed bag in terms of the people I have met and has made me keep a dynamic approach towards the people I have met and a static approach towards my core values.
