In the early days of running my own consulting business, I once met a prospect, who wanted to run for higher office: She was almost an hour late for the meeting. We spoke for about 45 minutes, out of which she probably spoke 40 (“lectured” might be a more appropriate word). Out of the 40 minutes she spoke, she pointed her finger at me for maybe about 30 minutes.
We never met again. She lost the election.
The lesson learned here is this: Overconfidence and arrogance are always losers.
