I don't get jealous. In my brain it's a pointless emotion.
But I do experience envy. Anytime I see another person driving a Lupo GTi, for instance, I feel a lil tinge.
My biggest source of contention though, is anytime I see a person truly in love with their job - like they've really found that which they were born to do...
I think, "I want that! Why not meeeeee?!"
I'm not alone in this wish, I recognise. But for some reason, my life seems to be just surrounded by people living the dream!
Gargghh! They mock me with their job satisfaction!
