Harry Connick Jr. – Nail Biting

Another nail-biter on this list is Harry Connick Jr., best known for “Hope Floats,” “Copycat,” and “The Iron Giant.” In a previous interview, he admitted that he won’t ever need a clipper because he could also do this on his toes! We don’t know how he exactly does it but we will leave that to our readers’ imagination.

Although this is a bad habit, this can reveal a lot of things about a person. According to BrightSide, the behavior could mean you are a perfectionist. A study showed that nail-biters are overachievers and people with type A personalities, who loved to overwork.
