From a post titled The Single Best Piece of Business Advice I have ever Received. Advice from a banker with decades of experience chose to share this advice with the author of this post …
“He told me that if I wanted to succeed I had to prepare better; dig deeper to uncover the real risks; anticipate questions and objections in advance; and generally research more and speculate less. At one point he smiled and said – “Son, I’ve had a very long and successful career because I always aimed to be the best prepared guy in the room.”
This advice struck me like a thunderbolt and I never forgot it. Since that day 21 years ago it has been a bedrock principle for how I have operate. In times of uncertainty it has provided me with some protection from calamities occurring. It has reduced the number of “surprises” I encounter to a minimal level. Ultimately, it has stopped me speculating and providing opinions unless they are well-thought through.”
