"A desk is a dangerous place from which to watch the world."—John le Carré.
It's so easy, isn't it? There's a meeting here, a phone call there; your email keeps filling up. The next thing you know... your calendar is loaded. But the ONE THING product marketing and management people need to build credibility is recent client experience. Jump ahead in your calendar a couple of weeks and block a full day for client meetings and phone calls. Time spent with clients (both customers and non-customers) is always time well-spent.
