that is a really fantastic point

I thought I was good at it until I hit 17-18, doing advanced mathematics. I really didn't understand Taylor series, and I just froze up on the calculations. You fall behind, and then the class just moves forward and it stops being fun anymore

I don't know the solution, but as you said - I went back into it later and it was much easier. Catching up those years inbetween was hard though!
