You are as good as your word.

In the world of acting, it is very important that information that you give others about yourself is completely accurate. One never lies or puts false information on his or her resume. That would be completely unethical and often you will get caught if you try it. If you are caught in one fabrication, maybe your whole resume is fake is what someone may think of you. Similarly, if you tell someone you are doing such and such, then you had jolly well be doing that. For this reason, it is frowned upon in the acting world to talk about what you are going to do because that is all too often just a wish or a dream and when it doesn't happen your veracity is againg challenged. Thus, if you make a statement, it must be true. And if you promise that you will do something, then you should follow through and actually do it and not blow it off. Also do not forget the committments you make and keep all of them. If you need to write in a notebook or daily planner that on such and such a date, you are going to do this or that, do so. Many of my greatest failings in my career were that I promised that I would do something and then forgot to do it. This almost always led to other things like retalitory actions from the slighted party. You really can't blame them. You broke your word, why should they have to consider you in their plans. Well, you get the idea. Nothing can be more important to the aspiring actor than to me a man or woman of his or her word.
