Many people find writing a great help here. And you say it works for you! Try to structure your involvement in discussions so you can prepare more. Some suggestions: Anticipate things that will come up in a particular meeting/conversation and write your thoughts down beforehand. When you feel really strongly about something in a conversation, don't start throwing arguments at the wall. Instead, describe your high-level concerns as succinctly as possible, and ask for an opportunity to get your thoughts together and email or discuss the next day. Pay attention to recurring themes, and write about them, the next time they come up you'll have cogent points to make. These won't work all the time. I suggest trying to move the needle on a few things you care about.
