First of all, you might not be popular with every colleague, which is frustrating for a newcomer of the workplace. So you'd better try to make a good first impression on all of your workmates, especially your boss. Furthermore, there probably is a gap between what you've learned at school and what you are required at work. You have to learn actively and quickly, and avoid making too many mistakes. Finally, the low payment for a new graduate and various living expenses make it difficult to make ends meet, so you may find yourself always on a tight budget.
