If I walk away from my DSTC job with one thing, it'll be the knowlege that I'm capable of building real software after all.
Learning to build software is a humbling experience: after a year away from uni, I think I'm finally starting to prove that to myself, as well as deciding that programming for a living may well not be my cup of tea.
What helps me is knowing that I still have something like thirty or forty years in which to be professional and become a respected hacker in my own right.
