Integrity is often measured by the tenacity with which a person sticks to his avowed promise, no matter the level of inconvenience it must involve to fulfil the promise
Once in a while, we wittingly or otherwise RENEGE on our promises

How often do you change your minds and do the opposite??

Whenever , this occurs , do you reprimand or forgive yourself??
