Canadian billionaire and former Shark Tank investor Kevin O'Leary revealed the most important career advice he received from Apple founder Steve Jobs. In an interview with The School of Hard Knocks alongside fellow investor Robert Herjavec, O'Leary shared that Jobs' guidance was both blunt and brilliant: "There's only three things you have to get done every day. That's called the signal. Everything else that stops you from getting the three things done is the noise."
O'Leary's Initial Reaction
O'Leary admitted that he initially pushed back, calling Jobs' advice 'nasty' and questioning why he should believe him. Jobs' simple response was 'Trust me.' Over time, O'Leary embraced this principle, which became a hallmark of his own career.
Steve Jobs' Philosophy of Signal vs. Noise
Jobs' philosophy of separating signal from noise was central to his leadership at Apple. In a famous 1997 appearance at the Apple Worldwide Developers Conference, Jobs emphasized that "focusing is about saying no." He cut numerous low-priority projects to concentrate on core categories, a decision that fueled Apple's turnaround in personal computing.
O'Leary's Career and 'Mr. Wonderful' Persona
For O'Leary, Jobs' principle became foundational. He co-founded SoftKey Software Products in 1986, later sold to Mattel for $4.2 billion in 1999—a deal that made him wealthy despite being disastrous for Mattel. Since then, O'Leary has built his brand as 'Mr. Wonderful' on Shark Tank, where his blunt style made him a household name.
Discipline and Purpose
Herjavec agreed that focus and discipline are common traits among the wealthiest people. "I've never met somebody with great wealth who doesn't have great purpose," he said. O'Leary added: "Billionaires don't care about money. They're on a mission."
The idea of limiting daily priorities aligns with modern productivity research. UC Irvine professor Gloria Mark, in her book Attention Span, found it takes an average of 23 minutes to refocus after an interruption. O'Leary's routine of picking three priorities and treating everything else as friction mirrors this science-backed approach to maintaining focus.
Beyond Jobs' anecdote, O'Leary and Herjavec urged younger audiences to learn AI and learn how to sell—two skills they believe will define future success.
