In general having a goal to exhaut textbooks by copying them is stupid. That's not what they are for. Get rid of that strategy.
Suspected as much... but I am not sure what strategy to replace it with. I definitely plan on doing all the exercises, and sometimes if I also write down some of the theory/proofs it helps with recalling them later. I'm guessing good rules of thumb are: stick to the essentials; use common sense; review at appropriate intervals.
I'm fine at asking a question that doubtlessly won't get removed. A question. I'm not sure that asking 20 (good, rule-abiding, thought-out) questions per week in a given forum would last me very long. That's about how often I might get stuck if I do some exercises every day.
On stackexchange nobody has a problem with someone asking a lot of question provided they are good, rule-abiding and thought-out.
You can also answer questions of other people. It might even be better than textbook problem because someone well tell you when you are wrong via comments.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
