It’s difficult to build something up but easy to knock it down.
Just as human beings are the most precious thing, so too is the work you do as an actor.
In acting class or on set your method of work must be kept secret and never gossiped about in the market place. Cherish, guard, and defend the hard work you and your fellow actors do. Don’t allow the culture of low level gossip seduce you into blabbing.
The work you do to make films and plays is a struggle and that struggle is called life itself.
It’s precious. Treat it as such.
