I like to start with a plan and the "why" behind it — once I can see how a piece of work fits the bigger picture, I can move fast and take real ownership of it.
Before that, though, I want the problem itself on the table, not the proposed solution. I think out loud, so a quick call almost always beats a long thread for me, and my questions are usually curiosity rather than pushback.
I'm happiest alternating between focused solo stretches and conversations with people who'll challenge me. Feedback-wise, direct and specific lands best; I'll take it in, sit with it, and come back with something considered.
The thread I'm actively working on is public speaking — getting as comfortable in front of a room as I am in a one-on-one.
