I think the key thing for me is interest. Like, I want to do something that I find engaging, challenging, and interesting. Something that keeps me on my toes. I want to be doing something that I feel passionate about, because if I feel passionate about it, then I'm gonna go the extra mile to help a patient, and I'm gonna give them a better chance at achieving better outcomes. I don't want to be stuck doing the same thing every day, because I can't deal with monotony haha.
People. Obviously, I don't really have much say over the patients I'll be seeing, but having good co-workers will be super important, because physio is a really collaborative thing. But like, this isn't just limited to physios - working with good OTs, doctors, nurses, social workers, etc. will a) help me give a patient a better outcome, and b) make work more enjoyable. Also like, just having interaction with people and connecting with them, is something I feel I need.
Good management is another thing. I think having a good boss can be key to having an enjoyable time at your job, and certainly not having to fight to get resources, have people understand the methods behind your work, and having the support of your employer, are all big things. People enabling me to do my job well in a good environment is definitely something I'll need to help me be a good physio.
As long as I'm happy in my job, I don't think I'd care so much about pay. Like, I'd rather be in an awesome workplace where I'm happy and love coming into work each day, rather than be in a job where I get paid a fair bit more but have to drag myself out of bed every day and don't feel passionate about what I'm doing. I'd also like to have my job close by, because physios tend to start reasonably early and having a long commute to and from work would just be draining, and would mean I'd have to sacrifice some leisure/relaxation/social time.
In the end, it all probably links back to things that make (and keep) me interested and help me feel fulfilled.
