What you are good at is narrower than you think

"Both stick with what they understand and let their abilities, not their egos, determine what they attempt." Buffett wrote that in his 1990 letter to Berkshire shareholders, about two pairs of managers he rated: Carl Reichardt and Paul Hazen at Wells Fargo, Tom Murphy and Dan Burke at Capital Cities/ABC.

It usually gets read as a warning against ambition. Stay small. Know your place. That is not what the sentence says. Nothing in it caps the size of what you attempt. It settles which voice in the room gets the deciding vote.

Both voices are always in the room. Ego is not the enemy of your plan. It is a co-author of it, and it writes well.

Ego does not announce itself

It arrives dressed as strategy. It sounds like adjacency. It sounds like we already have the customer, so the second product is nearly free. It sounds like the margins are better over there. Every one of those sentences can be true. None of them is evidence.

Ability sounds duller. It sounds like: we have done this before, we know which part we got wrong last time, and the operations manager who ran it still works here. That is what a competence claim looks like when it is real. Specific, repeated, and attached to a person you can point at.

When you cannot produce the second version, you are not making a strategic decision. You are making an emotional one with a spreadsheet attached.

You are not good at your industry

You probably describe your ability at the level of a category. Hospitality. Property. Software. Those are markets you operate in, not things you are good at. If the sentence describing your edge would also be true said by eleven competitors, you have named a sector and called it a skill.

The useful version is narrower, and slightly embarrassing to say out loud because it sounds too small. Picture an operator whose real edge reads like this: they open a new site faster than anyone else in the postcode, because of how they run the fit-out and the first ninety days of staffing. That is an ability. It also tells them which opportunities are not theirs. Yours should be about that size.

What eighteen years narrowed

I have built and sold five businesses over eighteen years. I made my first million at 28 and lost all of it at 40. The rebuild ran on a much shorter list of things I was prepared to attempt.

Owning and operating serviced apartments and hospitality venues with full P&L responsibility teaches this in a way no framework does, because the numbers arrive weekly and they are not open to interpretation. Raising more than $65 million across three rounds for companies I worked with taught me the other half: the difference between an ability and a preference. I am good at getting capital committed. That does not make me good at everything the capital then buys.

Chairing the board of an ASX-listed company through a CEO search and a relisting is the institutional version of Buffett's sentence. A search is a board naming, in writing, the ability the company needs next. The failure mode in any search is a board that hires a version of itself, because somewhere in the process the requirement has quietly been redefined as somebody's own history.

The refusal is the expensive half

Knowing what you are good at costs nothing. Refusing everything else has a price, and you pay it this quarter, in revenue you turn away and in people who conclude you lack ambition.

Which is why the refusal has to be spoken, with a reason attached. A no you keep to yourself is not a strategy, it is a mood. Your team will keep bringing you the same opportunity until they hear the sentence that closes it.

Start here this week

1. Audit last quarter's calendar. Mark every block where you were not the best person available for that task. That is your ego's budget, stated in hours.
2. Write your ability in one sentence that would be false if your closest competitor said it. If you cannot make it false for them, keep narrowing until you can.
3. Name two things you will not do this year, and tell the person most likely to propose one of them, before they propose it.

Do the third one on Friday. It is the only one that costs you anything, which is why it is the one people skip.
