In order to evolve, you should make sure you can do whatever you want even without any framework at all (stop relying on one single tool!). Check your basic knowledge. Do you know VanillaJS? Can you use it? Is there anything you still do not know about CSS, like specificity? Have you tried different approaches for your server, yet? Take a look at the differences between PHP, Ruby, Node.JS, etc. and find out how to implement ideas from other languages, which you think are good, into the language of your choice. Evaluate if it was a good idea. There are tons of patterns, ideas on how to do stuff and areas you might not feel at home, yet. All you need to do is explore what you still don't know ;)
You might want to check my article about basic skills or take a look at how I combined ideas from different sources in order to create added value.
