My favourite: back in 2005 when I finished my Bachelors degree I did some work setting up web payments for a local web shop. I followed the instructions exactly, used every trick I had learned and then some but got stuck several days somewhere around page 20 in the documentation on how to compile the module for Apache, something just didn't work but there was always just more thing I could try, and I assumed the fault was mine since I was just a student. One day I just gave up and mindlessly continued reading. Around page 100 there was a line something like: "This is how we used to do it, these days, just download this file, put it on this folder and use it like this: " Worked immediately. Now, I knew already back then that one should always read through the instructions before starting, but I usually think that means one chapter at a time, not the whole book :-)
