For most people, watching an instructor doing something - or even reading an excellent guide - is not the best way to learn a complex set of skills. Those might be critically important elements of your quest for excellence in some technical field, but unless you dive in and work through real-world problems on your own, you'll never truly master the material. Bootstrap IT's "Teach Yourself..." books present you with all the background and information you'll need to get started but, more significantly, they are designed to push you as quickly as possible out "into the field" where you can gain effective hands-on experience using the real tools of your trade.
