(CNN) -- A CNN Hero's journey to global recognition begins with a nomination by someone who's been touched by their efforts -- someone like you who wants us to share their story with the world. 

History has shown that great things can happen to those selected as CNN Heroes: 

• Andrea Ivory has nearly doubled the amount of free mammograms she's offered to underserved women in South Florida. 

• Doc Hendley, of Boone, North Carolina, expanded his sustainable clean-water systems on three continents as well as earthquake-ravaged Haiti. 

• Dan Wallrath, of Houston, Texas, and his organization, Operation Finally Home, doubled the number of homes they've built for injured veterans. 

• Anne Mahlum expanded her Philadelphia running program for the homeless into eight cities across the country. 

• Jordan Thomas of Chattanooga, Tennessee, has delivered prosthetic limbs to children in three countries. 

Do you know an everyday person changing the world? It's easy to nominate them as a CNN Hero. Here are some suggestions we hope will help you in crafting your nomination. 

• Think about what makes your hero special. Ask yourself: What makes my nominee unique? What specific accomplishment has he or she achieved that is truly remarkable? What impact has their work had on others? We encourage you to watch videos of previous CNN Heroes to familiarize yourself with the achievements of the inspiring individuals we honor as "everyday people changing the world."
