Growth is unexpected
I guess when you tell yourself that you are embarking on the journey of growth you prepare yourself for all the discomfort coming your way.
I know at least that is what I did. I had anticipated heartbreak and the discomfort of growth. Losing friends and relationships that I once felt mattered to me. There are some relationships you identify very soon in to your journey of growth that they will break off, and most of them, the ones that truly mattered to you, you expect different.
I might refer to relationships a lot here, but its anything really. Anything that comes your way during growth will most probably be unexpected. You can anticipate to a certain level or degree, however you can never fully fathom the journey of growth. No matter how different your story is and how self-aware you are, growth is the most constant inconstancy.
