Knowledge is only of value when you give it away. Laddermen don't scrutinize, we improvise. Learn and do it. What you don't want to happen will, what you want to happen won't. So be ready to Adapt, Overcome.
Chief officers save firefighters' lives.
There are no dead heroes. If you are a legend, people won't know about you and your service until you pass on. The best thing an old firefighter can teach a young firefighter is how to be an old firefighter. When arriving at a hazardous material incident, never pass a dead cop. Example - Lead by example.
