Principles
Durable claims that survive beyond the speaker's biography — each with explicit limits, transferability judgment, and evidence.
Principle
Culture is the operating system that scales the company — not a poster on the wall
Culture is the encoded decision-rule set the org uses when the CEO is not in the room; if it isn''t actively maintained, it decays in proportion to the org''s exposure to outside pressure.
For each foundational value, name the live behavior that proves it this quarter. If you can''t, the culture is stale — schedule the reinvigoration before the stress test arrives.
“Goldman Sachs has been around for 155 years. ... And Goldman Sachs's culture is unique, but I would also say it's constantly changing, and you better be working at defining what you want it to be and constantly reshaping it and amplifying what you think really matters.”David Solomon
“Culture is how people make decisions when you're not in the room. Culture is how you really scale.”Brian Halligan
Principle
Work on weaknesses, not just strengths — at scale you need the whole package
Long-term leadership requires the whole package: strengths plus actively-improved weaknesses, because the stress-tests come from many directions.
Inventory your top 3 weaknesses. If your last calendar quarter shows zero deliberate practice on any of them, you''re running the founder script — not the CEO one.
“You better be working on your weaknesses. Because if you're not doing all of the above — first of all, it's a random walk to begin with because there's so many talented people. ... I think you better be working on the whole package if you want to put yourself into the ring and have a chance to come out of the ring.”David Solomon
“He really taught me to be self reflective and really understand strengths and weaknesses, and be pretty hard on myself about things that I had to change if I wanted to advance. ... He had a profound, profound impact on me.”David Solomon
Principle
The decisions that reach the CEO desk are 51-49, not 90-10
Easy decisions get resolved at lower levels of the org; only hard, narrow-margin calls escalate. The CEO''s job is judgment under near-equivalence, not selection between obvious-good and obvious-bad.
Stop expecting 90-10 confidence on CEO calls. The job is calibrated judgment under 51-49; the alternative is paralysis.
“By the way, if it's an easy decision, it doesn't make it to my desk. One of the things I've realized is I don't have to make a lot of decisions.”David Solomon
“What's the best of two shitty options? Yeah, that is oftentimes what CEOs face.”Brian Halligan / David Solomon
Principle
Compass-keeping discipline — keeping your true-north pointed when noise tries to knock it off
The CEO''s defining skill is compass-stability under noise — decisions must be made from the true-north position, not from the loudest input in the room.
Build the muscle to say "we''re not going to do that" against momentum. The room''s consensus and your true-north are not the same thing — and the gap is where the CEO job lives.
“We all need a compass in these jobs, and you want that compass pointing north. ... It takes enormous resilience and determination to keep that compass — keep it pointed in the direction that you know is right while there's a lot of noise or agita.”David Solomon
“Somebody was suggesting something and there was a lot of momentum for it and he just said, Well, we're not going to do that. ... He was being a CEO, because he thought it was wrong.”David Solomon
Principle
Conduct the orchestra: clients, people, shareholders — all three or none
The three constituencies are coupled: failure to deliver for any one degrades the org''s ability to deliver for the other two. The CEO''s job is the coupling itself, not the prioritisation.
Audit your last 5 strategic decisions. If you find one constituency systematically starved, you''re not conducting — you''re soloing.
“I need to deliver for all three. And it's almost like as a leadership team, it's kind of like we're conducting an orchestra, and we've got to conduct the orchestra between clients, people, shareholders, and we've got to make it all sound beautiful.”David Solomon
“If you are not delivering for shareholders, you're not going to be able to do good things for clients. Because what do we deliver? We deliver people, capital and technology, and we marry those things together.”David Solomon
Principle
Smart-enough beats smartest — experience does the heavy lifting in 51-49 calls
High-IQ alone selects for solving novel problems; scale demands judgment from accumulated reps that only experience produces.
When evaluating senior hires, weight "has this person seen this kind of failure before?" higher than raw cognitive horsepower. Slope is cheaper to hire; experience is irreplaceable when the bumps hit.
“I'm in the camp of smart enough. ... You have to be smart enough, but the smartest person in the world without a whole package of other things, is not going to navigate Goldman Sachs well.”David Solomon
“Experience matters in these big organizations. And when it matters, it doesn't matter when things are going well. It matters when the bumps come. And you've got to make difficult judgments. And making those judgments, they're not 90-10 judgments, they're 51-49 judgments.”David Solomon
Principle
Serendipity and timing matter more in CEO succession than people admit
CEO outcomes are heavily contingent on timing of windows that the candidate doesn''t control; explicit acknowledgement is the structural defense against the hubris that takes successful companies down.
When telling your own success story, name the lucky breaks first. The hubris-defense is structural, not just modest.
“You know, Lloyd Blankfein got sick in 2015, and he decided that he was going to deal with his treatment and continue to run the firm and then come back. There are people who would have gotten sick and said, You know what? I'm sick. I'm going to step away. Had he stepped away, I wouldn't be CEO. ... If the succession had happened in 2013 or 2014 or 2015, it wouldn't have been me. When it happened, it happened in 2018.”David Solomon
“Those who fail to acknowledge the role luck may have played in their success and thereby overestimate their own merit and capabilities will have succumbed to hubris.”Brian Halligan
Principle
Second-mover advantage in regulated industries — you don''t have to be first
In regulated, levered industries, the cost of being early to a wrong call is asymmetric — fast-followers harvest the upside without absorbing the discovery cost.
In your industry, ask: is the cost of being wrong bounded or unbounded? In unbounded-cost domains, fast-follower beats first-mover — and the discipline that produces it is risk-management, not risk-seeking.
“When the world goes left, we think left is we go slower. You don't have to be first in financial services.”David Solomon
“The reason that lots of financial institutions go away is not because they have a risk-taking culture, maybe it's because they don't have a risk-management culture. So they make mistakes, and financial firms are levered and they get into trouble.”David Solomon
