That single question has saved me years of work, hundreds of thousands of dollars, and countless
mistakes. It works just as well in life.
Most of us inherit assumptions—about money, success, failure, relationships, education, risk, and what is possible. Many of these assumptions were never tested; they were simply repeated often
enough to become accepted.
As a product designer, I've learned every design has constraints. Some are real. Others only appear to be. Life works the same way. Many of the walls people live inside were never built from concrete—they're built from unquestioned beliefs.
One of the greatest advantages I've ever had wasn't intelligence, education, or money. It was curiosity. I've never been afraid to take something apart—sometimes an alarm clock, sometimes a
machine, sometimes an entire business model, and sometimes my own thinking.
Here's an exercise: Pick one belief you've carried for years and ask yourself:
• Is it actually true?
• Who taught me this?
• What evidence supports it today?
Innovation isn't limited to products. The greatest innovations often happen inside our own minds.

That may be the greatest invention any of us will ever create: our next version of ourselves.

Every meaningful improvement begins with permission to ask better questions.
The goal isn't to be right. The goal is to get closer to reality. Reality doesn't care what we believe. It simply waits for us to discover it.
Every time we're willing to question an old assumption, we move one step closer.
