Trying to wrap my brain around everything

After talking to my mentor, he's got me thinking it's stupid to learn to code: i.e., building websites from scratch is kinda antiquated.

So I'm going back to mastering Wordpress development, and especially using the Divi theme, as a career focus. But I'm still tinkering with HTML and CSS3, so I can tweak sites here and there.

Wish I could stay focused on learning one thing--so easy to go down rabbit holes.

For example, I was learning to build one website on a subdomain with my current website, to build my portfolio, but then got stuck going down a rabbit hole all about MAMP, then Bitnami, etc. OMG, it'd endless.

And every tutorial starts out with saying: Oh, I wish had had this back when I was learning. But it really doesn't have exactly the kind of tutorial I feel like I need that's geared towards learning specifically Wordpress, Divi theme, for development, along with marketing and some tutorials on tinkering the design to be specific with HTML and CSS3.

Are there tutorials for this that I don't know about?!? If anyone knows about one, can you please, please point me in that direction?

I just signed up for Lynda, but I'm still not finding something super specific to my needs. I'm having to bounce around from one course to the next, mostly because they're either too beginner or too advanced for me.
