I bought a good calculus book but never got around to actually learning it.
What finally worked was to start watching the MIT OCW lectures for multivariable calculus, which gives all kinds of nice physical/3d motivation - you immediately start working with vectors, cross products, all that fun stuff. And the professor is awesome.
Then once he referred back to enough ideas from Calc 1 that I hadn't learned, I watched all the lectures for the 18.01 single variable calculus course as well and finally saw why I should care about e.g. the derivative of csc(x)
All that provided sufficient motivation to do a bunch of exercises from my calculus book, which helps a lot obviously.>>9912460
