Think of your best mentor(s). What did they do right?
Be as specific as you feel comfortable being.
1. One of my first mentors had a huge lab (like, over 40 people). He made *everybody* learn each others' names. We had to submit our names and photos for online flashcards. There was a lab meeting where we literally spent most of the time going around and naming everybody in the room.
"If you continue in science, there's a good chance you'll interact with one of these people again. And when you do, you'll want them to know your name."
2. In the same lab, there were additional smaller groups, each headed by a grad student. Mine dedicated our first meeting to listing out our norms: expectations for how we'd behave when we were in a group. These could be serious ("Only one person speaks at a time") or silly ("We start all meetings by doing the wave"). But this really helped us feel comfortable expressing our ideas going forward, and got us thinking hard about implicit norms that exist in other groups (social psych lab, natch).
3. Current advisor has a dedicated yearly meeting with each of his advisees, where he addresses each of our long-term professional goals, and helps us set an agenda to reach those goals (even if his advice ends up being "reach out to my friend ____, who's working in the industry that you're interested in and can probably tell you more about what it's like and how to get there")
