“Maker” time requires large blocks of the clock to write code, develop ideas, generate leads, recruit people, produce products, or execute on projects and plans. This time tends to be viewed in half-day increments.

“Manager time”, on the other hand, gets divided into hours. This time typically has one moving from meeting to meeting, and because those who oversee or direct tend to have power and authority, “they are in a position to make everyone resonate at their frequency.” This can create a huge conflict if those needing maker time are pulled into meetings at odd hours, destroying the very time blocks they need to move themselves and the company forward.

Paul Graham embraced this insight and created a company culture at Y Combinator that now runs completely on a maker’s schedule. All meetings get clustered at the end of the day.

To experience extraordinary results, be a maker in the morning and a manager in the afternoon.
