After two decades of school and work, I have become accustomed to my educational and professional strengths and weaknesses.

It was determined early that I am not very good at math. I rely on a calculator for the simplest equations, not only because I can’t do them on paper but to avoid the embarrassment of having a figure wrong in addition or subtraction.

I am also bad at many sciences. Although I understand the elements of natural sciences like earth and physical, I’ve failed enough chemistry and geology classes to know I should stay away from those areas.
