Roger Bannister died last week.

Even if you don't recognize his name, you're aware of his legacy: he was the first human to run a mile in under 4 minutes.

More than simply breaking a record, Roger Bannister's greater legacy was proving to the world that limits are largely set by the mind. When we fail (or more accurately put, fail to try hard enough), it's often because we believe we can't succeed.

Bannister's example showed us that by changing our mindset -- by being open-minded to success -- we can change our universe of potential outcomes. The 'impossible' becomes possible.
