Article: Pain is not the unit of Effort
There seems to be a pervasive belief in society that pain is the measure of effort, as in common quotes like "No pain, no gain" and "What doesn't kill you makes you stronger". However, the concept of pain as a unit of effort can lead to detrimental practices that don't actually contribute to achieving our goals. Sometimes, we might be sacrificing happiness by pursuing efforts that are actually not relevant to our objectives.
The writer suggests two counterbalancing beliefs: "If it hurts, you're probably doing it wrong" and "You're not trying your best if you're not happy", which remind me of When things aren’t working, be smarter, not louder, and It is very simple to be happy, but it is very difficult to be simple.
