Paul, thank you for a post. Of course it is worth to start a job at government, but just if you have knowledge for that. Your question is quite strange, because both jobs at government and company could be your dream job. If you ask about the salary, so you can make a career and good money anywhere. You should choose what you want to be and after that you can choose where you want to start.
Yap, thank you for a question. It is not so bad, but if we talk about job at Mcdonalds restaurant, then it is really hard work with many hours per day while you stand on foot all the time. Mcdonald's itself is huge company with many employees and they have different departments, so if you start from the bottom and don't have any job experience, you can start at Mcdonald's and if you'll be good, you will have huge career opportunities. There are many people who started from waiter or cashier and after that they became restarant or country managers with very solid salary. Many people and specialists grows there, so the job at Mcdonald's is not the worst choice.
Ken, thank you for a question. There are many companies in the U.S. where you can start your career. It depends on you who you would like to be in the future. You can choose from bartender to attorney, from cashier to manager. If you think about office job, so i would recommend you to start as assistant at any office job where you will be able to help with papers. If you like to communicate with people and want to learn a lot - the first job as barista or waiter is a good decision. Job at restaurant will help you to understand people and communicate with them, you will see the money flow, will learn how people spends money, you will know a lot. So if you don't have experience, you have to decide what you want to be and to make a first step to your future career. Just don't forget to read many different motivational or biographical books to catch yourself at where you're the best.
