Query: A MUST for anyone being introduced into the world of Real Analysis!

Real Analysis is when math begins to get truly complicated for the graduate-level aspiring student, when you have to start looking beyond the linearity of mathematics and start to take a step back to see the big picture for what it really is. There are plenty of other books by other Authors on this topic, namely: Rudin, Gaughan, Wade, etc... But, for anyone who doesn't understand what is going on - these books will make you think that mathematics is impossible. Part of the problem with other books on this topic is that they assume that the reader understands and follows their every move, and if not, that they can work it out by themselves. However, this is a terrible mistake and Abbot makes no assumptions other than the absolute necessary basics. He realizes that he isn't writing his book for teachers and other scholars, and instead that he is writing for the student. He is writing for me.
