Be an Iceberg

As the phrase goes, don’t let your mouth write checks your ass can’t cash. Send along curated information that is a good summary of what you are doing, but be able to support it with research, opinion, or buy-in when pushed. Reveal enough to convey that you are a force, but do not reveal everything.

Do not operate at 100% capacity at all times, aim to operate at 80% so that when you really need to you can crank up your productivity in a sustainable way.

Always have a strategic reserve of competence.
