[Chris DuBois](/growthteam/chris) and I were talking this morning about ...  
Most if not ALL marketing is data driven now (we definitely focus on metrics, a LOT)...

###### There's a Risk:

❌ - It's not that hard for a marketer to have an over-emphasis on hitting a target and actually miss the bigger picture of becoming a great marketer by always doing great marketing.  
  
🤯 - Crazy to think, having metrics can create failure, if you apply them wrong!

Chris brought up Goodhart's Law.

It states,  "When a measure becomes a target, it ceases to be a good measure."

I was like... 🤨🤔❓  
  
In truth, I didn't really understand what Chris is saying here.  
  
I was like, damn, Chris is talking on another level of playing field I haven't graduated to. (nice!)  
  
So i played it cool... and afterwards.. I did what I've done a lot lately.  
I asked ChatGPT.  
  
The results are JUST TOO AWESOME not to share.

###### Thanks Chris DuBois 💪  
Thanks ChatGPT 🦾
