Maker Schedule
From Maker’s Schedule, Manager’s Schedule by Paul Graham :
One reason programmers dislike meetings so much is that they’re on a different type of schedule from other people. Meetings cost them more.
There are two types of schedule, which I’ll call the manager’s schedule and the maker’s schedule. The manager’s schedule is for bosses. It’s embodied in the traditional appointment book, with each day cut into one hour intervals. You can block off several hours for a single task if you need to, but by default you change what you’re doing every hour.

When you’re operating on the maker’s schedule, meetings are a disaster. A single meeting can blow a whole afternoon, by breaking it into two pieces each too small to do anything hard in. Plus you have to remember to go to the meeting. That’s no problem for someone on the manager’s schedule. There’s always something coming on the next hour; the only question is what. But when someone on the maker’s schedule has a meeting, they have to think about it.

When we were working on our own startup, back in the 90s, I evolved another trick for partitioning the day. I used to program from dinner till about 3 am every day, because at night no one could interrupt me. Then I’d sleep till about 11 am, and come in and work until dinner on what I called “business stuff.” I never thought of it in these terms, but in effect I had two workdays each day, one on the manager’s schedule and one on the maker’s.

When you’re operating on the manager’s schedule you can do something you’d never want to do on the maker’s: you can have speculative meetings. You can meet someone just to get to know one another. If you have an empty slot in your schedule, why not? Maybe it will turn out you can help one another in some way.
