Are you the kind of person who likes to do either?
I love giving advice because it makes me feel useful, but I have to watch out that I don't just come off sounding like a know-it-all.

Usually I'll only chime in when someone has asked for advice unless I know I can really help someone who will be receptive to it. Depending on who it comes from, I'm usually pretty receptive to advice from other people, but when it comes from my mother, my knee-jerk reaction is to reject it because it makes me feel like she thinks I'm a child, I guess. I've gotten pretty good and just smiling and nodding at her if it's something I disagree with though because I don't want to hurt her feelings.
