Understanding firsthand the impact charitable donations have on others is the most persuasive argument for giving.
Mitch Albom, the best-selling author of "Tuesdays with Morrie" and "The Five People You Meet in Heaven," travels to Haiti throughout the year to help run his charitable efforts there.
"Every month, I see the difference that being in a child's life — who doesn't have anybody to guide him — makes," Albom told CNBC about the orphanage his charity operates in Haiti.
"We actually have a music room now in our orphanage, where kids are playing drums and piano and guitars, and the talent is astounding. It's like we have these budding musicians I never would have known about. And of course, they wouldn't have known, if someone hadn't stepped in and given them an instrument."
Albom added, "In the end, we do really have enormous effects on each other's lives with the gifts that we're given."
For those who have the means but still have doubts, Kevin O'Leary, "Shark Tank" celebrity investor and founder of O'Leary Financial Group, known for his blunt opinions on television, provided a blunt assessment of why more people — celebrities or not — should give: "If you make money, you've gotta give some back, or you go to a bad place after you die."
