The problem with continuous learning

Conventional wisdom is that you have to be learning continuously, constantly acquiring new skills.

The problem with that is no one tells you what you need to be learning.

I'm improving my translation skills constantly by translating, but I've just never stumbled upon anything where I thought "You know, it would be helpful if I could take a course on that." I do employer-mandated training like WHMIS, but I just never come upon anything that I'd like to improve that can be taught in the classroom.

I'm the kind of person who can pick up new software very easily - I don't actually require classroom training to use new software - but that's very difficult to do when you can't actually think of anything to use the software for. For example, I have Photoshop. But I can't use it because I've never had to use it for anything except converting images. Some people improve their photoshop skills recreationally à la Worth 1000, but my creativity simply does not inspire me in that direction. It has never in my life occurred to me "Hey, someone should photoshop [idea]!" So I doubt I'm going to pick up any new software skills until I find the need or want to use any new software.

I would happily take any course my boss told me to, except that she doesn't, she usually just tells me to pick some courses that I'm interested in (and I'm not). I'd be happy to take a course if something occurred to me "Hey, I'd like to learn that," but nothing has so far. I'll happily learn any new software, but there isn't any I need or am actively interested in doing that requires new software.

I wonder if this means I'm getting old and set in my ways?
