(CBS) — More than 500 Harper College graduates got advice from U.S. Commerce Secretary Penny Pritzker Saturday during graduation ceremonies.

U.S. Commerce Secretary warmly congratulated Harper College graduates. She then explained why she accepted the offer from the school’s president, Dr. Ken Ender, to be the commencement speaker.

“My friendship with President Ender reminds me of one of the lessons that I have learned in business and in life: relationships matter,” said Pritzker.

Pritzker also left graduates with life lessons she says helped propel her to success.

“Take risks, be open and show up,” said Pritzker.
