Often, without meaning to, we make promises and break them, both to others and to ourselves. It could be that we say we will start going to the gym or that we say we will do a friend a favour, but then don’t.
When we break promises, no matter how small, we lose credibility with ourselves. We start to believe that we are unreliable and slowly our actions follow our thinking and we do.
If, however, we decide to go to the gym and we do it or we decide to get up when the alarm goes off, instead of hitting snooze, and we do it or we do the friend a favour when we say we will, then we will build credibility with ourselves and people will see that we mean what we say, that we are reliable and trustworthy. It is a matter of integrity, because integrity is a verb.
