Reddit reviews Calculus: Early Transcendentals

This one drove me into insanity

I would say that the best way to start is to pick a single book in Calculus, such as this or this or even this, and work all the way through it.

Then it is up to you; you could go straight towards Real Analysis; I recommend starting with a book that bears Intro in the name.

Or you could pursue a more collegiate curriculum and move onto Differential Equations and Linear Algebra, then Real Analysis.

I assume you are doing this all independently, so you should look at college sequences for math majors and the likes. You can mimic those, and look for online syllabi of the courses to make sure you are covering the appropriate material. This helps because it gives a nice structure to your learning.

Whatever the case, work through a calculus book, then decide what further direction you wish to take.
