(CNN) — (CNN) -- After losing a close friend to liver failure, Candy Chang spent a lot of time thinking about how she wanted to live out her days. Contemplating death brought clarity to her life, but she struggled to maintain perspective amid the daily grind.
She wondered whether other people went through the same struggle, and what mattered to them. She decided to invite others to share those thoughts by painting a chalkboard on the side of an abandoned house in New Orleans stenciled with the sentence "Before I die I want to ________."
What began as an experiment in making a public space into a shared spaceshas become a global art project, with more than 400 "Before I die" walls in 60 countries and 25 languages. It's been quite the journey for Chang, who did not launch the project with plans to expand beyond New Orleans. But it resonated among pockets of passionate people around the globe.
"Our public spaces are as profound as we allow them to be," Chang, an artist, designer and urban planner, said in an e-mail.
"Our public spaces are our shared spaces, and they have a lot of potential to offer us a more valuable and meaningful kind of life. I think about why we came together in the first place. Some of the earliest gathering places were graves and sacred groves. We gathered so we could grieve together and worship together and console one another and be alone together."
Many of the walls disappear a few months after they're "born," just like Chang's did, after someone bought the building and renovated it. Then, others pop up. Such is life.
In honor of the release of the first book celebrating Before I die's global footprint, we asked Chang to reflect upon the most common themes expressed in the walls. Hopefully, they inspire you to reconsider your hopes, dreams and aspirations.
"Before I die" came out of Chang's grief and depression, and the responses "have reassured me that I'm not alone as I try to make sense of myself," she said.
"Carl Jung said it's easier to go to the moon than it is to penetrate one's own being. Mental health takes as much exertion as physical health," she said.

"Love and be loved" is one of the most common responses on walls around the world, Chang said. She's also seen budding romance on walls.
"In New Orleans, someone wrote, 'Before I die I want to eat a salad with an alien,' and someone else drew an arrow and wrote 'Before I die I want to marry this person,' " she said.

Who doesn't have a long list of places they'd like to visit?
Travel can be the hardest thing to find the time and money to invest in, but that doesn't stop us from dreaming and plotting adventures.
"My family had a big white van that we drove all over the place when I was a kid," Chang said. "Ever since, traveling has been my school and my therapy. I've taken many road trips across America, and I worked in Nairobi, Helsinki, Medan, Johannesburg and beyond. Those experiences deeply shaped who I am today. It's made me more open-minded, reflective, compassionate, and grateful."

4. Helping others
Many of us say we'd like to "donate lots of money," "change a child's life," "help my neighbor" or "build a public school and a shelter." But putting others ahead of ourselves can be a tall order for some, especially in an era of instant gratification.
But, it's never too late, said Chang, and even the smallest gesture can last a lifetime.
"I'll never forget a middle school art teacher who encouraged me when I was full of self-doubt, a neighbor who fixed my bike pedal or a stranger who went out of his way to return my lost bag. Compassion lasts much longer than the moment."

"Making this project made me realize how much more I want to know my parents," Chang said. "I'm glad we're at a stage where we're good friends now, and I ask them fifty questions for every photograph from their childhood. Each week, my dad sends me endearing stories that only enhance the inspiring mythology of our lives."
