Most days contain more possible work than usable attention. If everything becomes a priority, your time is divided among competing promises. Research on goal conflict links that competition with strain and poorer well-being. Research on task switching also suggests that unfinished work can continue to occupy part of our attention after we move on.
This is why Steady does not begin with an inbox. It begins with a small set of goals and asks what today can realistically hold. A Tight day is not a lesser day. One finished step toward something meaningful can matter more than ten items copied forward.
Doing less is not the same as caring less. It is choosing where your care can become action.
In Steady, the limit is a boundary for planning, not a judgment about your ambition. You can still keep future tasks in Someday. They simply do not get to pretend they already fit today.
