Entrepreneur Reality Check From O’Leary In a post on X, O’Leary said entrepreneurship is not suited for everyone, noting the demanding nature of building a company.

"Not everyone is meant to run a business and that’s okay," he wrote.

He added, "Building a successful company takes execution, a willingness to take risks, and the discipline to work through long hours and uncertainty." O’Leary urged founders to ground their ideas in market reality before launching.

"Before you start anything, ask yourself one simple question, what problem are you solving that people are actually willing to pay for?" he said.
