"Sometimes the world can kind of be down and bad and I wanna change that," Lily Duncan said.
That started when Lily was six-years-old, but this year she's doing something a little different.
Lily has opened a charity account at Stuff Etc. for her twelfth birthday.
She has done this to support her friend Jaxton, and many others living with Batten Disease.
Batten Disease is a fatal, inherited disorder of the nervous system.
"I wanted to help do this for Jaxton because he's just so nice and he's like family to me," Lily said.
The account's called "Jaxton's Journey" and 50 percent of all sales made on the account will go towards Batten Disease research.
"For years there's been talk about that where in the past where somebody will say 'well I'm going to get you something for your cause and I'm going to get you an actual present for you' and she'll say they're both going to my cause," Lily's father, Ron Duncan said.
It's a selfless act for a friend in need.
"I like to help because it just kind of makes me feel good like I'm making a difference in the world," Lily said.
The "Jaxton's Journey" charity account is still open at Stuff Etc. in Waterloo.
Lily said it will stay open as long as people keep bringing things in for the account.
