Being creatures of habit can limit our ability to think creatively.
If you are a part of a standing, regular meeting, try sitting in a different seat, preferably one normally occupied by someone else. Enjoy the awkwardness when that person enters.
If its your meeting, insist that everyone sit in a different chair each time. Don’t let anyone get to comfortable with the status quo, in either the meeting or the office in general.
The status quo is your enemy.
