Time and tasks as a landscape, not a list. Point at any block.
Every task is a block, sized by the time it needs. The big ones look big, so you know what you're really up against before you plan a single day.

Blocks from the month become a chain for the day. Miss one and the rest shuffle along; nothing falls off the edge.
Start a timer on the block in front of you, alone or alongside friends, and watch it fill in.
