“There’s a companion quality you’ll need to be the leaders you can be. That’s the willingness to take risks. Not reckless ones, but the risks that still remain after all the evidence has been considered. … Certainty is an illusion. Perfect safety is a mirage. Zero is always unattainable, except in the case of absolute zero where, as you remember, all motion and life itself stop. … the biggest risk of all is that we stop taking risks at all. Purdue University President Mitch Daniels – Spring Commencement May 15, 2021, West Lafayette campus.
