When it gets really busy, that's the time when it's hardest to remember who you're there to please. It's not your boss, or your client, and especially not yourself. It's the people that make your clients matter. If you keep that in mind, all those other things seem to fall in place a lot faster. And if they don't, you're probably in a situation you shouldn't be in. Either that, or you weren't listening hard enough.
