Getting Motivated

What motivates people in factories to go to work every day? I know the obvious answer: money. But what makes them able to get up in the morning? Some kind of satisfaction in the parts that they make going into cars, airbags and other various components? I'm having a hard time getting motivated to write anymore, and I think it's just because I don't love it. I love writing blogs because I can show my personality and I feel a certain freedom from blog writing, but formal writing is hard for me to get into. Even Journalistic writing is hard for me to get into. Am I in the wrong biz or have I just not found my perfect job? And how many perfect jobs are out there? I only know of a few people who love their jobs, who say it's a perfect match. That means it can be found, right? But how am I supposed to know what it is? Going to college didn't help me figure it out, and the average person has 4 to 6 careers in a lifetime (the numbers go all the way up to 9 depending on the stats you use, which I think is a bit much). So where do I get the motivation to keep going? Money is motivating, but I don't see it every day, which makes it a weak motivator. I need to feel good about my job every day - I need to see something that makes me feel good about it every day. Am I just being nieve or am I being hopeful? Is that too much to expect from a career?
