A Complimentary Mindset involves choosing to intentionally notice (and acknowledge) those aspects that are good. Alerting yourself to the positive, and acknowledging it, complimenting yourself and others.
Why though would you choose such a mindset? In our perfectionistic society driven by both ambition and fear, the leaning has been towards preventing and correcting errors. Definitely a meaningful consideration, but unfortunately also a disabling one requiring a constant vigilance and attention to potential negatives and possible problems.
Accepting that errors are inevitable the question that begs asking is, does this mean that the achievements are irrelevant, that the accuracies are not germane. This is too often the case and the mindset, and so as the achievements and accuracies fall to the wayside, so too does the psychological and performance benefits of these.
Instead of instilling a sense of pride and capability we undermine it with an attitude of fear and sense of ineptitude. Making a conscious decision to notice and acknowledge the positives means developing a mind set in which not only are these achievements and accuracies relevant, they are also understood to be germane (indeed essential) to improving performance and maximising success.
