The Challenges of Starting a Career After Graduation
The recent years have witnessed a sharp rise in the number of college students who successfully start their careers after graduation. However, many others fail to do so because the transition from a student to an employee is actually full of challenges
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 impression on all of your workmates, especially your boss. Furthermore, there probably is a gap between what you learned at school and what you are acquired to do at work. You have to learn quickly and avoid making too many stupid mistakes. Finally, you may find you are always on a tight budget because of the low salary for a new graduate and all kinds of living expenses, which make it difficult to make the ends meet.
As the old proverb goes, “Well begun is half gone.” If you can handle these challenges skillfully after graduation, you will clear the path for further career development, either job promotion or starting your own business. So hang on and never give up!
