What skill would you learn intensely for a year for neuroscience?

I am very passionate about neuroscience. I'm not super passionate about the ways in which a lot of current neuroscience research is being done. I'm currently in a very fortunate position where I have a remote job that allows me to live somewhere with a low cost of living, and as such I will have lots of free time in the coming year to dedicate to learning.

The biggest goal for my career is to be very proficient at something that is in demand across multiple industries (still tangentially related to neuroscience, but things like robotics, cognitive science/intelligence studies, regenerative medicine, etc) that is not something an average job candidate could do. My biggest problem with this is that I am heavily interested in loads of things and get stuck with a bit of overanalyzing on where the best place to start is, and as such have a hard time getting started.

There are loads of smart people here on HN across a wide array of industries, and so I'm looking for some advice. Hopefully what you do day-to-day is related to neuroscience in some way, but I'm open to any and all thoughts! What I want to know is this: I have a year to dedicate to deeply learning a subject/skill/software/etc. If you were hiring in a year from now, what skill might you look for, if you could only pick one?

A deep thanks to anyone who takes the time to share their thoughts.
