An excerpt from firefighting; just change "fire" to "dive"...
"The most successful firefighters are not those who religiously follow every written rule to the letter, but those who recognize, accurately, their own skills and limitations. They take advantage of what they can do well, and mitigate the traits that could lead to an undesirable outcome.
The most dangerous firefighters are those who do not know what they dont know. When they were teenagers, they thought they were 10 feet tall, bulletproof, and knew everything. Now after fighting fire a little here and there, and taking some stupid risks without getting seriously injured or at times not even knowing they were taking risks, they think it can continue, which puts themselves, and if they are a supervisor, those around them in precarious situations."
