When Starship development was bottlenecked on Raptor engine production, that became the company's focus.

Not propellant loading, not heat shields, not launch infrastructure.

Raptors.

Elon gave it absolute focus, daily updates, memos to the company, resources redirected from elsewhere.

Once engine production broke through, attention shifted to the next constraint.

The limiter always gets the hammer.

Meme number two, push through roadblocks.

A roadblock isn't a reason, it's a problem statement.

You either clear it or you escalate it until someone does.

Admitting you're blocked isn't shameful at SpaceX, it's expected.

The cultural expectation is honesty about what's not working and the relentless effort to fix it.

That's another good line.

The cultural expectation is honesty about what's not working and relentless effort to fix it.

Meme number three, scrappiness.
