The fundamental principle that everything can improve might sound like wishful thinking, but without it being a valid principle, very little in human endeavour is of use.
Every situation can be substantially improved
Eliyahu M Goldratt and Efrat Goldratt-Ashlag
The principle leads to the conclusion that people are not fixed and can expand –the growth mindset. Remember the growth is possible because the outside was allowed to influence the inside. The person or system that grew is no longer the old system, it is an improved system with new potentials for growth, and so forth . . .
