Too Much Stress

 
After a lifetime in the construction industry, both as a structural engineer and as a builder, I've learned that there's always more than one way to solve a problem - and often the builder has the better idea. 
 
...but I'm not so sure about this guy.
 
Other brilliant things I've learned:  measure twice, cut once; the north arrow does not mean "this side up"; the boss may not always be right, but the boss is always the boss; treat people how you want to be treated; and all's well that ends.
