Friendships end in the same way roses die: they are beautiful, and then they are not.
I like the way the writer Steve Pressfield puts in his manifesto, Do The Work:
“The problem with friends and family is that they know us as we are.
The last thing we want is to remain as we are.
If you’re reading this book, it’s because you sense inside you a second self, an unlived you.
With some exceptions (God bless them), friends and family are the enemy of this unmanifested you, this unborn self, this future being.
Prepare yourself to make new friends. They will appear, trust me.”
