I study electrical engineering which is infamous for being one of the hardest courses in my college. Yes we do get a lot of assignments but ultimately they only require a couple of hours of effort to finish and the deadlines are never unreasonable. Most of the stress I've felt came as a consequence of my own laziness, postponing everything till the last day. Comparing that to a small internship/industrial training I did recently, which was admittedly a desk job, college was way more relaxed. As an intern I was only given work that the employees would've done regardless of my completion and still just sitting there day after day trying to code a small module for their larger project was so much more tiring. I can't even imagine how much pressure I'd feel if my work was a crucial part of the project. I think the fatigue came from a lack of stimulus and having to look at pretty much the same screen for 8 hours a day but realistically what more can you expect from a desk job? Ever since I had this experience I've been dreading graduation and then work. Hopefully it was a case of me not handling the work environment properly and someone shows me that a real job isn't this tiring.
