I design bridges for a living, based in Rapid City, South Dakota. Every complex engineering project I've worked on succeeded or failed based on the planning that happened before anyone picked up a tool.
I started noticing the same pattern in my personal life. The weeks I showed up with a clear weekly plan, written by hand, were the weeks I made real progress.
These are the inserts I made for my own binder. Every one prints at home, and an undated layout can be reprinted every year for the price of paper.
The best engineering is invisible. It just works. I want my planning systems to feel the same way.
