Every developer becomes aware of the concept of technical debt, whereby you make compromises in your design for the sake of some external force, such as schedule pressure.

If you are completely present, the external forces are no longer a problem, because there is only you and that external force, in this moment, and not a million other things you need to worry about.

Kinetic energy can be destroyed, but momentum cannot be destroyed in the absence of a net external force on the system as a whole.
