If you want to get your feet wet, spin up a virtual machine with something you want to get to know, and do stuff with it. Build things manually and learn how they all fit together, then try to repeat the process with automation. Through that, you can build a development environment that you know in and out, which you can then build upon using whatever technology/framework/language you decide on using.
