A great list of admirable qualities that actors should aspire to develop and incorporate into their personal and professiional lives, from veteran director, casting director and acting coach Risa Bramon Garcia.
All things being equal, unless you are as exceptionallly gifted and destined for iconic status like Marlon Brando and Marilyn Monroe--- both of whom were legendarily difficult to work with---most directors aren't willing to put with with a lot of BS from actors, nor do they have time to handhold. They are under a lot of pressure and on the set or in a recording session, time is literally money. It all boils down to if you want to work a lot, be someone that others want to work a lot with; be the solution to others' problems, don't add to them.
Backstage: "My happiness isn’t really determined by an actor’s decision to take care of him or herself. This is my own checklist for artistic sanity and success. However, when I do see fellow artists show us and embrace these actions, I’m gratified. We conspire together in our pursuit of happiness."
