@PhysInHistory I'm 61 years old. One of my goals is to learn, or relearn, all the math I learned in High School and College.
That means Algebra 1 and 2, Geometry, and Trigonometry. Eventually, I'd like to learn pre-Calculus and Calculus, which I never got to do in College.
@noveliciouss The whole quote is: "If you want to be a writer, you must do two things above all others: read a lot and write a lot. There's no way around these two things that I'm aware of, no shortcut" on page 145 from "On Writing" by Stephen King. Two pages later is where you find the above.
