Query: useless and confusing

I am prety good with computers, so one day I decided to get into programming. I talked to a friend of mine who programs for a living and he told me to start with visual basic. I picked up a copy of "Sams Teach yourself visual basic in 24 hours" and eagerly opened it up when i got home. I found the opening chapters over explained and repetitive, but despite my incredible boredom i forced myself to move on. I eventually read up to about chapter 10 when i became totally confused. The provided examples would sometimes not work, and it left me frustrated. So there i was, stranded in the middle of this book, consed, bored and frustrated. After that day, i put down the book, and i havent opened it since, and im happy i didn't.
