How will I make right decision for my future?

Decrease the time spending on having fun, but increase the time on study and seek suggestions from those excellent studetns to improve the efficiency. Good luck~

Best way, keep concentrating on your studies and give it your top priority. No matter the outcome the result will give you opportunity in all fields. If you don't study the opportunity will decrease which will cause you more headache. Even if you do not know what you want to become or do, if the results are there you can decide later when you get the results because you might run into a situation, or experience more life which will dictate what you want to do as a passion. Sometimes passion does not lead to money but satisfaction of work. Sometimes if you go for money the job you do won't make you happy but the end result with money will overcome your happiness. Find the balance.
