I am a CS student, but I have had a lot of student jobs related to my studies. At most workplaces, they appreciated my skills and abilities, but being able to only work 1 day a week, the tasks I get assigned are not of any real value to the company, and I suspect my managers never really cared if I finished them. Since nobody cared about what I did, I quickly got demotivated, and I usually ended up browsing Hot Questions on SO, IRC, and HN. These sites look somewhat relevant, and did not cause any suspicion, like Facebook or Twitter.
Now I am soon to finish my degree, and get a full-time job. However, I am really anxious whether I am actually able to work for 8 hours in succession every day, 5 days a week. University is a lot of work, but it is scattered throughout the day. I am not sure if I have ever programmed for more than 2 hours in succession. Programming 8 hours a day seems like an incredibly burden, and mentally unbearable...
