Without a fixed, believable deadline, you can’t work calmly. When you don’t trust the date, or when you think it’s impossible to do everything someon… - Jason Fried

Details reveal themselves as you use what you’re building. You’ll see what needs more attention. You’ll feel what’s missing. You’ll know which potholes to pave over because you’ll keep hitting them. That’s when you need to pay attention, not sooner.

Imagine the day of an expert who frequently gets interrupted by everyone else’s questions. They may be fielding none, a handful, or a dozen questions in a single day, who knows. What’s worse, they don’t know when these questions might come up. You can’t plan your own day if everyone else is using it up randomly. So we borrowed an idea from academia: office hours. All subject-matter experts at Basecamp now publish office hours. For some that means an open afternoon every Tuesday. For others it might be one hour a day. It’s up to each expert to decide their availability. But what if you have a question on Monday and someone’s office hours aren’t until Thursday? You wait, that’s what you do. You work on something else until Thursday, or you figure it out for yourself before Thursday. Just like you would if you had to wait to talk to your professor.
