I'm constantly invoking this principle, but I have a small tweak: combine it with the (now anachronistically named) Python Paradox to get "use a tool from your toolbox".

Restricting the number of different technologies in your toolbox gets you most of the benefits described in TFA. But contrary to "boring", it's actually preferable for some of those tools to be bleeding edge. That way you also get to enjoy the benefits of the Python Paradox.

Of course, you need to have good enough taste to pick new techs, and sometimes the bleeding edge will cut you. But because you amortize that cut over the whole org it doesn't hurt much.
