I've made quite a few difficult decisions. But in the end they were necessary. I can't tell you which one was the hardest, because I don't think I know the answer myself. I've decided to let friendships go, as much as I hated to. I've decided to let guys go, like Gerhard for example. It was a horrible decision, but it had to happen. If not for me, then for him, as well. I've switched jobs, which is not a nice experience for someone who doesn't like change.
What about you?
