I graduated from the university with a degree of engineering．It is a good field but my heart was not in it．I wanted to be an actor or work in the entertainment industryliving a creative life．My choice of engineering was really a mistake but I realized too late．As soon as I graduated，I moved straight to Los Angeles—the home of the film and television industry! I tried to get a job in that field．I often worked as an extra in movies and TV shows—standing in the background while actors are in the foreground．This was fun for a while，but I wanted a real acting job，where I was speaking! Sadly，in Los Angeles，there is too much competition．Every race and age is represented：old，young，black，white，Asian，and Midwestern types like me．Being an extra couldst make enough money for me to live in Los Angeles．I had to do something else for money． After three years of trying，I gave up my dream of being an actor and started a different career．I then tried network marketing，but in the end，that failed．Seven years after graduating from college，I was still in debt，still searching for a satisfactory life．I decided to go back to engineering． However，I was starting to get disappointed with my life．Why is life not like what I expected? I expected to have made a lot of money，gotten married，with a house and nice cars，kids，freedom，etc． Millions of people lead lives with their dreams on the shelf , existing but not really living. I wanted my life to be different，more satisfactory，more alive．I wanted a life filled with adventure，romance，friendships，Successes，and dreams realized．But America was not providing that for me． … Struggling in the US?
