I usually find a glowing review about any book or dvd, I am considering purchasing, at the cafe. *rolls eyes*
I also found that people there tend to believe it is wrong to learn from a DVD. I guess they aren't aware of vark and the different learning styles.
Nothing wrong with DVDs unless you really want to learn magic and have tangible resources that won't go out of date and not be usable when Microsoft makes their next OS upgrade . . . I've got over $500.00 worth of material I can't access because of Windows 7 (I'd kill to get back on XP, the last system MS came out with that wasn't a POS)
Books are an amazing resource in that you will get far more information out of them for the dollar invested and not just tricks! You will learn how to spell, punctuate, use the proper form of a word (such as their, there or they're) when writing or posting and then we have the history of magic as well as life lessons that many authors share as anecdotes throughout their texts.
By All Means, it's oft times easier to learn material when you can see the action. For years that was about the only way I could learn certain moves but the old timers would make me read and re-read the material a few times so that I EARNED the hands-on help and proved that I wanted to learn how to do Magic rather than Tricks. But as things unfold in life and you start realizing that you're not able to make the real money that's out there and your knowledge is more or less limited to the latest trends, remember your grumbling over the sarcastic old fart that called you on your lethargy today and that said old fart might actually know a little something that will help you go further, faster with your magic and the quality of your knowledge than any DVD is going to give you . . . and that includes some of the better quality pieces I'm aware of that are on the market.
