Struggling to find fun ways to learn

I love web development and I know (HTML, CSS, JS, JQUERY, PHP, RAILS, SASS, and Grunt). I learn tons from YouTube and web development sites but I've learned a ton and I'm running out of resources especially when YouTube content contributors don't post. If you know any good sites or channels etc, anything really that you use I'd love to know. I want to focus more on rails and all the languages mentioned above.

Thanks in advance! - Junior Web Dev Leyton H -
