Bella Gonzales didn't have a birthday list this year for her 11th birthday, instead she had a mission and made a promise that she would donate toys as holiday gifts to the Children's Hospital in Pittsburgh.

With the help of her parents, the 11-year-old girl started her mission by posting her goal and plans on Facebook. In just two days, already fifty people committed to help and give donations. Strangers dropped of their gifts at Bella's house and received more than five hundred donations from people across the country.

The young girl was inspired by her cousin who's spending time at the Children's for cancer patients.

"Think about all the people who are going through a lot right now and think about what you can do to help them", Bella's inspiring message to everyone.

On Tuesday, Bella carried out her mission to provide happiness to other children and delivered more than 500 toys to Children's Hospital.
