If you’ve never heard of Dave Ramsey, Jim Collins, or Patrick Lencioni, then you’re missing out. That being said, get introduced to their material on leadership here. These guys have had a large amount of influence on leaders all around the world.
Have you ever been caught off guard by behavior of others and realized later that you are doing the same thing? How about driving slower than some traffic in the fast lane? How about discovering you have 11 items in the 10 items express lane? This sort of frustration can lead a tired, grumpy individual to lose their cool and sometimes cause some real anxiety where none was needed.
In dealing with others at various levels instead of getting frustrated get real: tell them you’ve done it, too (assuming you have), turn it into a teachable moment, and steer the in the right direction. It takes a bit of humility, but can really change the dynamic of a situation.
