BOULDER, Colo.- Many have seen an invention and said, "Why didn't I think of that?" A University of Colorado student had an idea, but she ran with it and is now in her second year of running a successful business.

Jessica Saba is the granddaughter of the man who invented medical I.D. bracelets that show a person has an allergy or medical condition. Her grandfather taught Jessica early on to save her money, so when an opportunity arose, she had the cash to take action.

Those who haven't been in a college classroom lately probably have no idea about the i>clicker. It's a $30 remote control that students buy and are required to have at an estimated 700 colleges and universities across the country. Each student has a unique I.D. -- the remotes are used to take attendance, among other things.

"Teachers are able to ask a question on a PowerPoint and students are able to instantly give their response," Saba said.

Saba was a sophomore at CU when the idea hit her one day in class.

"I noticed when our teacher said to click in that everyone raised 300 identical i>clickers.

Her idea for the clicker sticker was borne.

"I thought to myself, 'We personalize everything as students.'"

She created 17 designs and is now selling them in nearly 20 bookstores in seven states.

Saba's business made a profit the first year and is on track to turn and even bigger profit the second year.

Saba is a senior and when she's not studying for her six classes, she's looking for new ways to grow her business.

"I would love to get the clicker sticker in to more bookstores."

She's targeting the 700 college and university campuses that require students to buy the i>clicker.

Saba still hits up her grandpa for advice as business grows, but she credits his advice to sock away cash for being able to execute her invention. She's never taken out a loan.
