What makes a good police officer?

Probably a dumb question, but I am trying to get into law enforcement after the military, and part of me is having a lot of negative self-talk. which I feel is just the anxiety that comes with trying something new. So, my question is, what can I do to become a good police officer and a proactive one? What are some traits that good police officers have? I apologize if this question is dumb, but it's a genuine question. Thank you.

Edit : Thank you all for the advice I didn’t really expect this much of a response but I truly do appreciate it!
