It crazy that he was so confident the ship would sink he was willing to stranded, and he was right. I can hardly think of anything I am that confident in.
His wiki article says he immediately regretted rashness in saying he rather stay on the island but the captain refused to take him back. So it seems he may have been more talking shit for effect rather than genuine and then got lucky.
Yeah, that's called instinct triggered by practical knowledge and a sense for survival, used to come quite handy in those unpredictable adventurous days!
I have often been confident that software won't ship based on the current team and hit it right on the money. Tons of folks see a startup and just nope outta there because they can tell it's a wreck waiting to happen. I'm sure you are giving yourself less credit than you deserve. You can tell when things are bad in an area you have worked in for years.
