"There are two types of people - those who come into a room and say, Well, here I am! and those who come in and say, Ah, there you are"
This is a quote by Frederick L.Collins and I'm relatively sure he means that going 'here I am' is a positive thing, you know, people with charisma, presence all that.
Mostly, he's probably right. If you're a suit it's brilliant to be able to hold a room but if you're a planner, as is usual, it pays to look at this from a different angle.
If you want to work well with suits, clients and creatives they have to know you won't steal their thunder or take their credit.
That also means not holding the room in the palm of your hand, but taking the time to let everyone else talk, listening well, and when you do say something, making them think.
