Whether we are trying to repair a relationship, or improve ourselves, or succeed at something great, it is critical that we don't get complacent as we start to see change and progress. It is critical that we not let down our guard, that we are vigilant every moment, that we are practicing our new tools and skills every moment, because if we assume we've locked in the changes when we haven't actually given it enough time, we are likely to regress and slip back into old patterns of self-sabotage and failure.
