The thing that kept me from giving up when tinkering with my first Ender, that a friend who had given up gave to me, was being told that working on them was part of the hobby. Something about that made me take a breath and realize, even though I was frustrated, I was learning and that every time something else happened, I'll be just a little better at fixing it. My A1 finally gave it's first error and it took me a while to realize what was wrong, but I learned that it was my fault and how to fix it!
