To be brief, when studying modeling I learned that I must be: believed, I must look good for others, walk as a model even if it is not and in general only worry about my physical and what others think of me, until I am Rude with other people with certain actions that they teach you, that and less be humble and be a good person since that would only make me meet whatever people , poor , etc.
But I just take the good things from my modeling classs of course.
