Designers deal with an aggressive schedule from time to time. And by "from time to time" I mean: Every. Single. Time.
We face the perils of an impossible deadline, and we come out on the other side, frazzled, bleary eyed and smelling faintly of coffee and missed opportunities.
We will stay up all night if we need to (and we do in fact need to) to get something awe inspiring ready for that morning meeting. This deadline will be completed. And there will be coffee and doughnuts.
Because we are designers, and we will get through this.
