Several of you asked about the program at the Johnson & Johnson Human Performance Institute I attended earlier this week. Hard to capture the experience in 300 words, but the fundamental insight it is built upon is this: Most executives are skilled in managing their time, but the bigger challenge they face is managing energy—physical, emotional, mental and spiritual. And managing energy requires understanding the patterns of stress and recovery that build strength and endurance. I can’t say I’ve mastered the new skills after just three days, but I’ve certainly made progress. One lesson that hangs over it all: have a clear sense of purpose and mission; that helps the other pieces fall into place.

Meanwhile, take some time today to watch Susie Gharib’s interview with HP CEO Dion Weisler. He talks about his decision not only to make gender and racial diversity a priority at his company, but to require his suppliers to do the same—or else lose HP’s business.

“If you want to make a difference, be prepared to make the tough call. And so we did that,” Weisler says. “That’s the power of being in the leadership position. That you can influence an ecosystem. That you can step up and lead as a leader across an organization larger than your own to make a difference in the things you really believe in.”

Weisler says it’s the right move, and also important to his employees. “They want to work for a company that cares about making a difference in the communities where we serve,” he says, “and so for us, it’s a business imperative.”

Passing on a Test

The University of Chicago sent a jolt through the world of prestigious universities yesterday by announcing that it will no longer require U.S. applicants to submit ACT or SAT scores. The school's dean of admissions and financial aid said he doesn't want “one little test score” to end up “scaring students off” who are otherwise qualified. Other colleges have abandoned standardized test requirements in recent years, but U-Chicago is the first top-10 research university to jump on the test-optional wagon. Washington Post

Brexit who? Despite the U.K.'s impending divorce from the European Union, commercial real estate in London continues to garner hefty price tags.
