• When we say someone “is bipolar” rather than “has bipolar disorder,” that’s like saying that someone “is cancer” rather than “has cancer.”
• Perhaps depression is the absence of hope.
• I became an expert at camouflage. Hide in workaholism, hide in alcoholism, show no vulnerability, do no serious self-inquiry, and have no hard conversations. In other words: get no help.
• I came to perceive my job as, if not a mood stabilizer, certainly an antidepressant. By demanding so much of me, by insisting that I show up and keep the lights on at the company, the business gave me a purpose that transcended my malaise.
• I wonder if I would have been able to pull this off were it not for those frenetic episodes of elevated mood that bipolar disorder made possible.
• We buy things we don’t need, with money we don’t have, to impress people we don’t like.

On relationships:

• Ingredients that spell doom between partners are criticism, contempt, defensiveness, and stonewalling.
• It occurred to me then that the best way to build influence with someone is to accept their influence to begin with.
• I am who I say you are.

On business:

• When you work at a private equity, your bosses buy and sell companies, mostly with other people’s money, and earn outsize returns by leveraging those investments with debt.
• Information technology, software, and the developing internet made possible asymmetric returns that you couldn’t access in businesses where you had physical inventory and real estate.
• I realized that the most self-confident leaders are not the ones who need to talk, but the ones who ask the best questions.
