Imagine for a moment that you are the Captain of a great sea voyaging vessel setting out on a journey to an island you’ve never been to before, but you know has many great riches. The weather is fair, your maps point a clear course, and everything is going in your favor.
However, as you set out on your journey, you discover that your crew members have started to grumble — it seems they have doubts as to whether the island exists, whether the ship can actually make the journey, and whether they really deserve the riches, should they find them. The crew decides to mutiny, turn the ship back around, and head for the port where they came from.
That seems a bit silly, doesn’t it? Not deserve the riches? Even though everything was going well, and you, the Captain, knew exactly where you were going and what you would find there, they still had doubt.
Unfortunately, we do this to ourselves all the time. We sabotage our own endeavors by overthinking the whole thing, casting doubt on ourselves, and reverting back to our old habits.
