I you aren't willing to invest the energy and effort to do that, all the video watching won't do anything for you. It will get you 5% of the way at best. The true learning comes from staring at a problem for hours, trying 100 dead ends, and then finally having an insight two days later while taking a shower that suddenly make that intractable problem seem trivial.
These things aren't mutually exclusive. I don't know about anybody else, but I'd rather watch a video of a human explaining the subject, then sit down with a textbook and start working through problems.
> you can't sit thru lots of pages of mathematics text
Even if you watch those videos, you still need to sit through lots of pages of mathematics if you want to master the subject.

(The first two are "MOOCs" recorded in the 1970s! probably the first ever recorded MOOC, even before the internet, and the lecturer is absolute gold)
