I have no words of wisdom for you, but can certainly sympathize. What you said here caught my eye because these are the very words I have always used to described math. I COULD NOT understand it. I wasn't dyslexic with numbers, it just didn't make sense to me - like a mental block. Like you, I did well in other subjects but barely had the math credits I needed to graduate. Now, here is the irony. What type of work have I done for 20+ years? Worked in a CPA office! And I have always been praised by my bosses. The change for me? The lowly calculator! For the first time I felt like I had control over the numbers.
I hope your years experience will count for a lot rather than a piece of paper. Good luck boss mare.
