Here's a meaningful career for those inspired by St Francis of Assisi. Taking care of God's creatures, from cute little dogs to scary snakes, takes years of study and dedication. It's not a glamorous job, and your patients may not always be able to show their gratitude, but taking the time to help fellow creatures in their time of need is something that truly makes the world a better place.
