When you don’t succeed, you beat yourself up.
You don’t take action, and you still beat yourself up.
When you finally do take action and you don’t get it right straight away, you again beat yourself up.
You don’t take action, you hurt yourself. You do take action, you hurt yourself. I hope you can see where I’m going this.
If all you’re going to do is to whack yourself either way, why even bother trying? What you’re doing is defeating the purpose of actually giving something a go.
