The only way that you can find people with high integrity is to spend enormous amounts of time with them over a longitudinal period of time. So, it's not about 2 weeks of 10 hours a day; it turns out to be 5 or 6 months of many, many, many hours every week. And the reason is because, eventually, their integrity shines through/their lack of integrity eventually seeps to the surface because you just can't hide it forever.
