I commend you for your attitude with regard to partying while in school. More students should understand the value of the education they have available to them. You will obviously do well.
I would like to point out to you one curious event in my early professional life. I was interviewing for my second position within my original employer (government contracting firm). The interviewer spoke to me about my academic record and the activities in which I participated on campus. I told him of the committees on which I served, how I taught CPR, I was a Teaching Assistant and a "First Aider" (student computer lab consultant), and Vice President of the Jewish Student Union. He seemed suitably impressed with the fact that I carried a full-time load, worked 20-30 hours per week, and held those various posts. I thought the interview was really going well until he asked me a question out of the blue. He asked, "Why didn't you have a 4.0 average?"
I probably went pale for a moment as the vision in my head was a rejection letter, but I decided to be straightforward and answer it "the way it was." I told him, "It wasn't my goal."
It was his turn to take a second glance at the interview. He told me he was not expecting that answer and wanted to know more. I explained how I felt that I had to have good grades (nothing less than a B was a good grade and a semester was not successful unless the QPA was at least 3.3) but I was there to do more than acquire a good QPA. I was there to learn how to manage my time when faced with conflicting priorities. I was there to learn the organizational skills necessary to hold the posts I did. I was there to learn, and I was there to enjoy being a student.
When I was done, he shook my hand and said, "Congratulations. You just got the job over 3 4.0 students who will probably NEVER understand why."
So, the moral of this overly long story is: Always keep a sharp eye on your academic and civic performance, but don't forget to have some fun while you're at it. That counts too.
