Just read a post on the comments section and wondered how would things be different had I answered a few questions differently.

Have you seen the movie "Butterfly Effect" ? If not, go and watch it.
The film explores the life of a boy, who when he reaches college realizes he can use his journals to go back in the past to specific events and by changing one little detail, can completely change his "present".

A must see for anyone who feels that he messed up his interview! :)
