Eschew the ordinary, disdain the commonplace. If you have a single-minded need for something, let it be the unusual, the esoteric, the bizarre, the unexpected.
You can eliminate depression without making someone happy. You can cure anxiety without teaching someone optimism. You can return someone to work without improving their job performance. If all you strive for is diminishing the bad, you'll only attain the average and you'll miss out entirely on the opportunity to exceed the average.
