At first glance, the idea of meditating to ground yourself in the present, to view things in terms of 'here-and-now', has little to do with design or usability.
But consider that design is about making decisions.
Your ability to make good decisions is affected by the extent to which you feel an obligation to stick with a course of action that you've already invested time and resources in.
This doesn't mean you should change course whenever things get difficult, but consider your motivation when you feel the need to continue on with something that isn't working. There is a real difference between having reason to believe things will improve and being stubborn because of the investment you've already made.
The previous investment -- the "sunk costs" -- is less valid than your present understanding of the situation.
Momentum and inertia both refer to movement. You want the positive trait of momentum. You don't want the negative trait of inertia.
This post came out of a piece I read from from UC Berkeley's Greater Good Science Center:
Can Mindfulness Improve Decision Making?
