In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.

Never Hit A Girl…Unless She's Armed
September 29, 2014
Sun Tzu and Miyamoto Musashi made no distinctions regarding gender. To them all adversaries were defined as combatants.

The Ground. The Dirty, Filthy, Dangerous Ground - April 29, 2013
The Raiders fan had biceps that could put Hulk Hogan to shame and a physique that was nothing short of awesome. He stood out in a bar full of average guys, not only because he was ripped, but also because he was the only person cheering for the other team, the only one doing it vociferously anyway.

Shu-ha-ri - The Phases of Mastery in a Dojo and with a Pen - September 19, 2011
It’s not unusual for martial artists to talk solemnly about “the Way” and how the life lessons that have been created through training spill over into the rest of our lives.
Channeling Sekishusai - July 18, 2011
One of the most important aspects of martial arts training (and the thing that first attracted me to the activity) is the linkage between things of the body and things of the spirit. There’s a lot to be said for the physical aspects of training—and if most people are anything like me, it’s almost addictive.
