On the job, you have to care about what other people think. Often, you have to care about it more than what you think. You have to document your work, and produce test plans. You have to execute part of someone else's plan, or prepare a plan such that someone else can execute part of it. You have to juggle multiple tasks. You have to write status reports and attend meetings; if you're lucky there isn't a lot of this. You may have something enjoyable to work on, only to have that task cancelled or indefinitely shelved when you're many weeks or months into it and it's 85% complete, and then be put onto something that you like a lot less.
