What are you upskilling in?

Im having a bit of a "too many interests" problem. There are so many jobs I could do. I know I need to buckle down and focus on one. How did you decide?

I was thinking something with data, administrative assistant, finance or nursing (going back to school and paying for that is holding me back!)

I took some data analysis courses and the field is still super interesting but studying after I worked all day has been tough.
