Do you ever feel like people optimize for looking successful instead of becoming successful?

Every day I see posts about:
waking up at 4:30 AM
reading 100 books a year
cold showers
productivity hacks
morning routines
But almost nobody talks about:
failed projects
losing money
bad hires
deals that fell apart
months when nothing worked
The most valuable business lessons I’ve learned didn’t come from success stories.
They came from mistakes.
What’s one business mistake that taught you more than any success ever did?
