Speaking for myself personally, for the longest time I never saw myself as anything more than what I had chosen as my career. My career had created my identity, in turn my life followed my identity. The idea of change was so overwhelming and fearful, that when an opportunity presented itself to force change, I had to take it.
Is creating an identity so important, that we often forget to create a life? Becoming specialists in our identity often conflates with our life to the point that we are often not sure which personality is truly who we are.
Our identity is malleable, we can always create a new one. Our life is something very deep and personal. Not every interaction is a sell or a potential client.
Sometimes its just life.
