I have tried to look at some of the proofs out of the book, and while some I think I understand (like the delta-epsilon stuff), some I cannot follow at all. Even worse is that I can usually follow them but I cannot understand how someone could possibly think up some of the steps. I have never had a class that stressed learning this stuff so I really don't understand proofs altogether.

I guess my questions are - should I worry about this now? and where could I find resources to help me understand it better. Any advice is welcome thanks.
