Love that von Neumann quote !

I have had this experience, that I've moved much faster learning to use math tools when a friend much more advanced than me suggested that I can use a tool even if I don't know how it works. It's like if I stopped building a house because I want to see if I can build a hammer myself !

(Well, this is also my experience programming, implementing the low level stuff myself is a much more attractive exercise than actually assembling off-the-shelf parts into something people would actually use!)
