Envy

Human beings have a natural tendency to envy others whether for looks, fame, relationships, or etc.. As we feel this certain feeling, we crave and desire strongly for something that we don't have and see in others; we can even feel easily upset or angry because obviously life hasn't treated us unfairly. However, taken back into perspective, this emotion "envy" is actually a glorious form of human race, where we realize that there are people out there better than us in some specific area, and therefore wish to be changed, while subconsciously praising others for their unique qualities. In other words, envy is based on appreciation, but whether we appreciate or not, determines whether it will be transformed into jealously. As complex as this seems, this whole process can take just one second to successfully deprive us of mental "satisfaction".
