Two Filmmakers.

Christopher Nolan.
Guy Ritchie.

I consider both of them successful in their own rights. Yet they approach their craft differently.

Nolan doesn't just make movies. Ritchie pretty much makes movies every other year. Yet not all Nolan movies are masterpieces, and not all Ritchie movies are horrible. 

Nolan has more good movies than bad ones. Ritchie also has more good movies than bad ones.

I love spotting the fact that not one single road leads to success.
