Watching videos as a very poor way to learn technical topics. Buy a $45 book covering your topic. Find a quiet place to carefully read it on a regular. Practice what you’ve learned. Repeat as necessary.
Videos are very nice for learning how to replace a broken garbage disposal or how to upgrade your laptop to 4 gig. Problem for the Video Professor – YouTube has plenty of free material on both those topics.
However, I agree, videos — or even books, although a decent book will get you started — are not the way to learn complex computer applications. You need to install the app, then use it to accomplish progressively more complex tasks. Each time you run up against something you don't understand, turn to Google (not the Video Professor, not Borders, B&N, nor Amazon). Before you know it, you will be an expert.
I used to be a big consumer of computer books (and vendor manuals, neatly housed in loose-leaf binders). No longer. Now it's just dual monitor — what I'm working on in one, and Google in the other. I work until I hit a snag, then turn to Google for the answer. Much easier than indexes, card catalogs, etc.
