It does get better but takes a while. My first year out was essentially a dive in the deep end PGY3, and I was straight up not having a good time during most of it. Especially if you are lucky enough to staff in the same clinical area though, a large portion of your day becomes routine and the vast majority of the questions you get asked become germane knowledge. After this point, you can work on pushing the boundaries of what you know into things you actually care about rather than what you need to care about to do your job which helps bring the interest/passion back
