This guy doesn't even include Pareto principle in his guide to success. This guy has us working most of our time getting coffee.

I say, better to write the script without a job and produce a 2 min trailer with your friends and show a couple people, than to work for months serving coffee that you hate and only to work on a script you can't complete.

[I don't support balls to the walls philosophy, only do stuff that gets results, be ruthless about efficiency. Activity is not productivity.]
