Struggling in the US? Move to China!

I graduated from the university with a degree of civil engineering. It is a good field but my heart was not in it. I wanted to be an actor or work in the entertainment industry…living a creative life. My choice of civil 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!

For three years, 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 thousands of blondish-red haired Midwestern types like me. Being an extra couldn’t 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 college, I was still in debt, still searching for a satisfactory life. I decided to go back to civil engineering.

However, I was starting to get very 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, time freedom, etc. Millions of people lead lives with their dreams shelved, existing but not really living. I want my life to be different, more satisfactory, more alive. America was not providing that for me…

In addition, America was too expensive—always worrying about money was a headache. I wanted a life filled with adventure, romance, friendships, successes, and dreams realized.

…

I decided to move to China.
