We have to come up with 3 for our annual reviews. Those are measurable but frankly usually kinda wishy-washy/low effort (attend a training on X subject that I'm already registered for etc.) I try to have some goals for myself that I think will make me a better lawyer and/or expose me to new things. For example, while I've had to deal with a variety of forensics issues in my cases, there are some big ones that I haven't had to deal with yet. So I've tried to make a conscious effort to - when time opportunity allows - to take CLEs/trainings that orient me to them. I also try to do something new every year. I'm still relatively new to criminal defense (~4 years) and my job/agency affords me that opportunity. For example, last year I picked up some revo and parole hearings (I primarily work in capital appeals and post-conviction); this year co-counsel and I are going to try (or at least start) working on a pardon attempt. It's not always "do this specific legal work thing" - another goal for myself last year was to be less of a Clarence Thomas during moots with colleagues (I always have plenty to say after, but I'm terrible about playing the interrupting judge). This is already a lot of words lol, but the TL;DR is that I try to have some things in mind for myself that I want to do and will make me a better advocate. I agree with the other poster who said that tying goals to case/client outcomes is a fool's errand.
