Communicate, always.
Just like over-hydration is a rarity, similarly over-communication is rare. Especially when the style of communication is concise and clear.
Effective written communication makes it easier for the recipient to read (or skip) and to reply if a reply is needed.
It allows us to share the relevant information with the people who we are engaging with and helps them get clarity without needing to make assumptions. This reduces the time needed for synchronous meetings, and also helps in maintaining and growing trust and reliability.
It might require us to gather the courage to share where we might have dropped a ball. But if we get good at sharing, it's likely that we will drop fewer balls.
