Yesterday I wrote a post (see here) about the prove-it mentality and how that mindset propelled one Atlanta-based company from five people to a behemoth worth tens of billions of dollars that trades on the stock market.

Today I read a quote from Mark Twain that reminded me of the story from yesterday’s post:

It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.

Being certain about something you haven’t proved to be true and being wrong about it can get you in trouble. Having a prove-it mentality helps you avoid that situation.
