An actor/actress for a professional career can be very exciting, but it also very exhausting. The stars work from morning to night, with very few days off, saying the same lines over, and over again. Plus, the directors, and producers have a certain time to get the movie, or sitcom done, or else they will lose money. Most of the actors/actresses especially if they have a big role, take a vacation before staring in their next film. Another thing is that your life is not the same, as it used to be. Making a movie, or doing a sitcom takes up all your time because you are working night and day.
Finally, I think this is a bad idea as well because every job has a down side to it, whether it is working in a office, working for a doctor, or even working for a plumbing company, every job can be very exhausting. He, or she should do whatever they want for a living, as long as it makes them happy. This is all relevant because these are all objections to the last cause, which is that it is an exciting job.
The best solution, is if you want to become an actor/actress in life, and that is your goal, well, go for it. Nobody is stopping you. Like my father always said to me life is like a ship crossing an unknown seaport, always looking for that point of light. As long you strive for that point of light, you will eventually reach your goals. "By setting your goals, making plans, and organizing strategies, you are exercising your control. By recording your thoughts, and writing down the actions we plan to take, your self esteem grows" (McTigue, ix).-CH
