What are the perils of Jealousy

the most obvious thing i can think of is the mortal sin i guess. However the more possible thing that could happen if you are too jealous of something is that it can cause yourself trouble. When you want something really bad, often times you could cause yourself alot of trouble to obtain the thing you are jealous of and thus losing alot of valuable things on the way. Being jealous of things could also cause people to blind. I suffered in jealousy over something that someone had and i tried everything to obtain that thing. In the end i was so blind over that particularly thing i lost track of the people around me and the valuable things that was there for me. The biggest perils of jealousy would probably be this sort of blindness to things that are important in life.
