My early mentor had a saying that resonated with me — “Avoid Wishful Thinking.” I’ve found that advice has served me well over the course of my 30-year (and still going) career. Living by that credo can take quite a bit of discipline and resilience. There will be pressure to do “good enough” when it’s reasonably questionable as to whether what is being presented as “good enough” really is minimally acceptable. In the business of life safety, the minimum matters: tread lower with great care and discretion. Unfortunately, when it comes to smoke control, I’ve come across many who still apparently believe in “close enough” with a healthy dose of “wishful thinking” on top.
