Jamie Dimon: Why ‘Sloppy’ Communication Kills Leadership – and How to Fix It

What Jamie Dimon Says About Sloppy Communicators

Jamie Dimon, CEO of JPMorgan Chase, believes too many leaders are sloppy communicators. In a recent podcast, he said that careless communication is a major weakness for ambitious professionals. According to Dimon, disciplined communication is not a soft skill—it’s a core leadership habit that drives faster, smarter decisions.

Why ‘Sloppy’ Communication Hurts Your Career

A sloppy communicator does not organize their thoughts before speaking. They ramble, use vague words, and confuse their audience. Dimon warns that this lack of discipline makes leaders seem unprepared and untrustworthy. In contrast, great leaders structure their thinking intentionally. They make every word count.

The Jeff Bezos Example: Six-Page Memos

Dimon pointed to Jeff Bezos as a model of disciplined communication. At Amazon, Bezos banned PowerPoint and required executives to write six-page memos. These “six-pagers” forced leaders to think clearly, sharpen their arguments, and make better decisions. Many Amazon alumni say this practice was the most valuable leadership lesson they learned.

The Rule of Three: A Simple Structure That Works

Dimon also shared a practical tip: the rule of three. Instead of rambling, present information in three clear points. For example: “We have three options—A, B, and C. Here’s why I recommend B.” This structure helps people remember and act on your message. Dimon uses it himself in shareholder letters and speeches.

How to Stop Being a Sloppy Communicator

• Prepare before you speak. Think about your main point and how to say it in three clear parts.
• Write key messages down. Like Bezos, use written memos to organize your logic.
• Avoid filler words. Get straight to the point. Don’t pontificate.
• Ask for feedback. Check if your audience understood your message.

Key Takeaway

Sloppy communication reflects sloppy thinking. To become a great leader, practice disciplined communication. Use structure, write your ideas, and follow the rule of three. As Jamie Dimon says, it’s a discipline that earns trust and drives results.
