Simple vs. complex

I spent some time this evening struggling with a problem set working through some complex ideas involved with one of my classes.   Erin, who is always supportive of such efforts was curious about the underlying ideas...   I went through a quick explanation of how even a small mistake in a study can create a great deal of misclassification and error.  She thought about my explanation for a second and summed up all my efforts and struggles in a simple idea, "so little things make a big difference?"

Exactly...

And I hope a motto to live by as well...
