Punishment feeds itself.
There is no growth in self-criticism.
We conflate it with self-improvement. We do that because most of our growth comes from executing, and no one is successful all the time.
So, inevitably, we fail. And when that happens, it’s easy to self-criticize.
Self-criticism doesn’t help us grow. We satisfy a superficial urge to “punish,” which only feeds itself.
What I am saying is that punishment simply reinforces punishment. It doesn’t help anything, or anyone else.
If you fail, quit, or stop, it’s ok. Just understand where you are, and move forward.
There is no penance in beating yourself up, just more pain.
