Caterina Fake, who, with her husband Stewart Butterfield, founded Flickr, knows a thing or two about bliztkreig work schedules. But she points out that late nights are seldom very useful in the grand scheme of things. Hard work? Overrated:
When we were building Flickr, we worked very hard. We worked all waking hours, we didn't stop. My Hunch cofounder Chris Dixon and I were talking about how hard we worked on our first startups, his being Site Advisor, acquired by McAfee--14-18 hours a day. We agreed that a lot of what we then considered "working hard" was actually "freaking out". Freaking out included panicking, working on things just to be working on something, not knowing what we were doing, fearing failure, worrying about things we needn't have worried about, thinking about fund raising rather than product building, building too many features, getting distracted by competitors, being at the office since just being there seemed productive even if it wasn't--and other time-consuming activities. This time around we have eliminated a lot of freaking out time. We seem to be working less hard this time, even making it home in time for dinner.
Much more important than working hard is knowing how to find the right thing to work on. Paying attention to what is going on in the world. Seeing patterns. Seeing things as they are rather than how you want them to be. Being able to read what people want. Putting yourself in the right place where information is flowing freely and interesting new juxtapositions can be seen. But you can save yourself a lot of time by working on the right thing. Working hard, even, if that's what you like to do.
