What Should I Know Before Studying Differential Geometry and Topology?

[ice109]

it sounds interesting, what should i know before i try to study it and what would be a good intro book to read?

note this isn't just a book request

I say this,

The classic text is DoCarmo's 'Differential geometry of curves and surfaces'.

You should know real analysis of several variables but of one variable is very viable.
