My manager has given me feedback that I could be more active in meetings, which would help me find my place within the team. However, I find it hard to participate in meetings a lot of the time, because I don't know the technical source material they're talking about. This leads to me learning as I'm in the meeting, and I don't have any remaining mental bandwidth to speak up.
When it comes to meeting types, I'm good with those like retros and brainstorms but those that are more technical like tech reviews and project planning can be hard to a large voice in.
Write down a core question/discussion point on a sticky note before walking into the meeting.
I sometimes get lost/sucked into the discussion of the meeting, and never say anything. But the sticky note provides an anchor to a say something which is relevant.
