This sounds kind of obvious but I think people can sometimes get drawn up in the excitement of growth. Growth for the sake of growth, however, is parasitic behaviour that leads to the eventual death of everything around it.
If you are happy, you don’t need to change. Only upkeep is required. If most of your life is great but you have a nagging feeling that something needs work, be specific about what and why you want to see change so that you can ensure the best outcome for your entire life. Not improve one area at the loss of another.
