Master is a strong word, but I'd love to 'master' WordPress this year. I have worked on a number of WordPress sites and they have all left me with less than favorable views of WordPress, so it's been something that I have actively avoided. I'm wanting to see if the reason I was avoiding it was just because my own misunderstanding of it made it more complicated and frustrating than it really needed to be. At that point, I will then be able to make an educated decision as to whether WordPress and I should continue dating.
I've been reading this awesome php book (PHP and MySQL Web Development by Luke Welling, Laura Thomson) and have been watching a bunch of wonderful WordPress videos on Develop with WP's YouTube Channel. I'm also headed to WordCampNYC next weekend, I'm sure my brain will explode from that! Next step will be to find a good project to work on with it, and that's where the mastering will really start to happen.
