What I have had truly learned from the Father of Quality Management Dr W Edwards Deming back in the early nineties:

Point #1 of his 'Fourteen Points of High Performance Management':

Create Constancy of Purpose for Continous Improvement

- Plan for quality for the long term;

- Don't just do the same thing; find better things to do;

Transposed to the personal setting:

To truly succeed in any endeavour on the Highway of Life, you must fully embrace continuous and never-ending improvement as a living element in whatever you do, making it the basis of your habitual domain.

By the way, his Point #1 resonates readily with the First Principle of Personal Success Achievement as postulated by Napoleon Hill, in the 'Law of Success', written in the 1930's.
