To add few more points on this, work on side projects. I have to tell, how a side project can help you. For example, I was very comfortable using React in my project. I thought of building a simple preview container (for different sizes from desktop, mobile, tablets), where user can drag and drop few components, position them etc.
I'm in the initial phase of this and guess what, its really helpful. Making you uncomfortable at times (as in this case for using React to position components on the fly, which I had never done before) helps a lot.
