@Jam3sHambright @BauerOutage Hah this was my first thought too…. But it doesn’t stop there. Angels. Marlins. Giants. Rockies. Twins. Royals. White Sox. Etc etc. And there is a long list of players who have been given second chances to play in professional sports again too.

This was a good new learning for me…

“You upload PDFs raw. One page = 3,000 tokens.

Fix: Paste the text into a Google doc. Download as .md format. Under 200 tokens.”

Good stuff 👇

[Ruben Hassid @rubenhassid]

The $20/month Claude plan is enough.

But only if you stop making these 17 mistakes:

1: You upload PDFs raw. One page = 3,000 tokens.
Fix: Paste the text into a Google doc. Download as .md format. Under 200 tokens.

2: You build files inside Cowork too early.
Fix: Plan in Chat first. Move to Cowork only when you know exactly what you want.

3: You write 500-word prompts that reload.
Fix: Write 29 words instead: "I want to [task] to [goal]. Ask me questions using AskUserQuestion."

4: You say "redo the whole thing" to correct part 3.
Fix: "Only redo section 3. Keep everything else. No commentary. Just the output."

5: You send 3 separate messages for 3 tasks.
Fix: One message, three tasks. "Summarize this, list the points, suggest a headline."

6: You type "No, I meant," stacking on the history.
Fix: Click 'Edit' on your original message. Fix it. Regenerate. History replaced, not added.

7: You use the Opus model for a grammar check.
Fix: Sonnet or Haiku for quick tasks. Save Opus + Extended Thinking for deep work.

8: You dump 50 files into Cowork "just in case."
Fix: Only include what this task needs. Zero folders for quick tasks like email drafts.

9: You never restart fresh & keep having long chats.
Fix: Every 15-20 messages → summarize, copy the brief, start a fresh session.

10: You keep 3 topics in 1 chat. Claude re-reads all.
Fix: New topic = new chat. Always. Dead context is dead tokens.

11: Your about-me file is 22,000 words (too long).
Fix: Trim to under 2,000 words. End sessions with "Write a session-notes.md."
Paste my .md file prompt: https://t.co/j5fEzSGxlT

12: You leave search & connectors on by default.
Fix: Default everything off. Turn features on per task, not per account.

13: You upload the same PDF to 5 different chats.
Fix: Use Projects. Upload once. Every chat inside references it without re-burning tokens.

14: You skip Personal Preferences & waste setup.
Fix: Settings → Personal Preferences. Set your tone and style once. It persists forever.

15: You rewrite prompts from scratch every time.
Fix: Keep a prompt library. Same structure, swap the variable. Stable prompts get cached.

16: You manually run the same report every week.
Fix: Use /schedule. "Every Monday at 7am, create my weekly briefing." Wake up to a finished doc.

17: You use Claude for things it can't do.
Fix: Know your tools. Images → Gemini.
Real-time search → Grok.
Stop burning tokens on dead ends.

Well that ends the debate on deaths in Gaza.

Hamas itself is admitting that 80% of casualties were combatants.

There was never a genocide.

You have been lied to and manipulated.

[Keith Rabois @rabois]

Shut Harvard down.

[David Collier @mishtal]

This is what remains of a Kindergarten in Rishon LeZion are an Iranian ballistic missile attack today.

Expect absolutely no media coverage whatsoever - and no angry condemnations from "human rights groups".

[Eyal Yakoby @EYakoby]

Not a single actor, actress, or singer has said a word.

@Mike_Kurland Great content - keep it up!

[Mark Jacobson @mark_jacobson]

@heistjm No Eldridge? What about leagues where Caglianone qualifies as a 1b?

[Mark Jacobson @mark_jacobson]

Give me 7 games of World Series baseball… Dodgers vs Blue Jays or even Dodgers vs Yankees… over that Super Bowl.

[Dan Clark @DanClarkSports]

TOTAL PAYROLL 2010-2025

$4.4B, New York Yankees
$3.3B, Los Angeles Dodgers

WORLD SERIES TITLES 2010-2025

0, New York Yankees
3, Los Angeles Dodgers

[Mark Jacobson @mark_jacobson]

@BBGreatMoments Did not expect to see the Angels there…

[Mark Jacobson @mark_jacobson]

I have zero problems with deferring salary. Good for the Guardians to keep their best player… but go spend some money and get better players around him!

[Yahoo Sports @YahooSports]

Seven-time All-Star José Ramírez and the Guardians are working on a new seven-year extension worth $175 million, per @hgomez27.

The contract includes $70M in deferrals, per @JonHeyman.

[Mark Jacobson @mark_jacobson]

Yep… this is the right take

[Blake Harris @BlakeHHarris]

Freddy Peralta finished 5th in Cy Young voting last year while the Brewers made the NLCS

Trading him away because Brewers ownership doesn't wanna pay him is worse than the Dodgers spending money, by the way

[Mark Jacobson @mark_jacobson]

This cycle won’t reward everyone equally: some will grow, some fold, some aggressively acquire to fill gaps.

The common thread: positioning. Not optimism. Decide before the next wave hits how your firm will operate, and you’ll capture disproportionate share

[Mark Jacobson @mark_jacobson]

I keep hearing search firm leaders say, ‘We’ll invest once the market fully comes back.’

Here’s the thing: the rebound already happened. Just not evenly. Some firms saw it last year. Some last quarter. Some now. The winners aren’t waiting for a green light.

[Mark Jacobson @mark_jacobson]

They’re doing the hard work: retraining teams, redesigning workflows, committing to a different operating model. And yes — those firms are seeing growth, not because the market got easy, but because they’re structurally ready

[Mark Jacobson @mark_jacobson]

[Mark Jacobson @mark_jacobson]

Hot take: AI isn’t making executive search easier. It’s making it more honest.

When research, mapping, and outreach compress to minutes, what’s left is judgment, influence, and trust. Some firms get stronger. Others get exposed.

Wrote more on this here 👇

[Mark Jacobson @mark_jacobson]

AI makes average recruiting cheaper.

It makes great #executivesearch more valuable.

That gap is where the market is moving.
