Very interesting! Personal professional development is one area that I always lag behind in. I am usually so busy fixing everyone else's issues that I don't have time to focus on myself and my own learning. That being said, I do have a project I am looking forward to learning and trying out this Summer. Posts will definitely be forthcoming!
For it can be hard to know what to study as I am not sure what I will work on next, but it may help to have some experience of this field.
Enjoy your learning.
