Life is not without any pain. There's good pain and then there's bad pain. Good pain feels like receiving genuine feedback. It hurts but it builds you up. Bad pain kind of feels like being judged. It hurts and it breaks you down.
Fortunately for me, the lesson I learned only involved a pair of shoes.
Nevertheless, there's something to be learned from either one. The challenge is in the latter. How to let go of the source of pain, before it gets any worse.
