Hi RDW –
Welcome!!
I learned WordPress simply by experimenting with it. I recommend getting a free WordPress.com website and just have fun with it. Maybe make a blog documenting your adventure in learning WordPress or anything else you might like to share with people.
I think that you’ll find the help within the site to be more than adequate to learn with until you have specific questions but I also really love Lynda.com for learning software (this is a paid tutorial site).
There are also numerous WordPress experts who write tutorials and information on their own blogs (some paid and some free). I really like Carrie Dils, Bill Erickson, and Sridhar Katakam although they all write primarily about using WordPress with Genesis which is a paid premium WordPress framework that I use a lot.
The Elegant Themes people put together this article about places to learn which I think has some pretty strong suggestions as well.
I think it really comes down to how you learn best. By the way, great question! I hope this information helps.

Yep, same here. I started 10 years ago experimenting, making lots of mistakes. Google is your friend. So is this website, so is Stack Exchange.
It’s print (remember that?) but the WordPress for Dummies book is a good introduction.
