There are varied definitions of strength but one of its most overlooked types is the strength to keep trying. This type of vigor is invisible to the naked eye but is felt through the heart. I know many people who are hanging by a thread, getting by in life, and hiding behind their seemingly perfect social media profiles. Usually, the people who love to make everyone laugh in the room are those who have it the hardest in life. These happy-go-lucky people have a positive disposition, and that’s why it’s easier for them to use humor to avoid vulnerability.
