Jo Dee Messina has officially kicked off her 'A Million Doors' campaign. She needs to raise $2.3 million for the Nashville-based non-profit Holy Trinity Montessori School.

The school teaches children everything from math to people skills, and helps them develop a love for learning.

By making a minimum donation of just $1 you will get an exclusive new song called "Carry Me" that Jo Dee recorded specifically for this cause. The songwriter Jared Anderson waived his publishing royalties, and Jo Dee released the song independently thanks to her record label, which allows for 100% of the proceeds from the song to go directly to the cause.
