Excellent post.
It is important to be able to recognize the difference between a black and white situation, and a grey one.
Black & white has a right answer. 2+2=?
Grey doesn't. Red is the best color to mark danger.
Many engineering types have a hard time with grey questions, as they run contrary to our training, which tells us there is always an optimum answer.
If you want to be a know-it-all, then either really know it, or do the research to make sure you're right before answering. Being right a lot
can make you overconfident. Again, beware.
I wish I had known this when I started my career. It took 15 painful years to figure this out. I'm OK now...
