Becoming a theoretical physicist was one of my aspirations after reading Stephen Hawking's A Brief History of Time (understood half of it, give or take) and being good at Physics in high school. Really appreciate the effort to categorise every steps and resources necessary to attempt this field.

But at the same time this is starting to seem daunting... how long would it take to go through all this material on a part-time basis? Well, my original plan was to do it after I semi-retire.
