Vicious circle

Have you seen the Max NewYork Life ad?
It is lovely. It shows hows in a moment life comes back full circle.
First a guy with long hair who is jogging or crossing the road passes a guy with a wonderful bike and wishes he had one...
Then the guy with a bike sees a couple on a bike and wishes he had a gf too on his bike...
Then the girl who is sitting behind the other guy on the bike sees a lady playing with her small kid and wishes she had a kid...
The mom passes past a jewelery store, sees a diamond necklace on the window and wishes she could afford one and sees that an old guy is buying that necklace for his wife...
The old guy while travelling in his car see the first guy with the long hair at the signal going past him and wished he had hair too... cos he was bald.
They show this in a 30 second ad i guess...
How true is this...
we come across something we see and wish we had that too...
that is how life is i suppose...
