First, I am very self-disciplined about the role. For a truly excellent actor, if he wants to make a role and the whole city full of three-dimensional sense, he needs not only very vivid acting skills, but also great changes in external form to meet the role setting. In order to make a good movie, amirkhan can lose weight and gain weight in a short time, and Xiaolizi can gain weight quickly in a short time in order to better conform to the role in the play. These require extremely high self-discipline of stars, testing their control over desires.
Second, being a star is a high-risk occupation, and life is often in danger. Although a star looks beautiful on the surface, being an actor is a very risky career. In film and television dramas, many wonderful pictures are presented to us, and all actors need to risk their lives to do these actions. Stars have accidents because they are filming everywhere. These accidents have huge casualties, but they still choose to stick to it professionally.
Third, the competitive pressure is great. There is never a shortage of new people in the entertainment circle, a career with very low threshold, so many people will be integrated into the entertainment circle. This puts a lot of pressure on everyone, because if you don't work hard, you will be eliminated. This is not only physical pressure, but also mental and psychological pressure, so many stars have mental illness.
