Nested Sigma Noation

What's wrong with analysis? I hope to learn complex analysis some day. It seems useful.

Complex analysis is not real analysis. Complex is actually fun, its just another class where you manipulate numbers and variables and see cool things. You don't really deal with super technical proofs because it's kind of assumed you already sucked at that in real analysis, and it's kept a little easier.

Real analysis is mostly proofs. Hard proofs. Extremely technical. Just for the sake of being hard. Most of the homeworks were silly things like "Prove this theorem", and you're like "but that theorem is obvious!" and then the proof turns out to be really subtle and you only get half credit for writing it poorly. Without an amazing teacher, the class inevitably sucks. No teacher at my school is amazing at teaching it.
