As America marks 250 years since its founding, I've been reflecting on what has always struck me as this country's greatest strength.

Not just one revolution, but millions of them.

The scientific breakthroughs that challenge accepted wisdom. The entrepreneurs who build what others say can't be built. The immigrants who come here to imagine a different future for themselves and, in doing so, help shape a better future for all of us.

As an immigrant and American by choice, I've experienced firsthand how this spirit of reinvention continues to define our nation. I believe our willingness to question, discover, build, and begin again is one of America's enduring competitive advantages, and our greatest source of optimism for the future.
