Do you ever feel like coding is like gambling, when working on personal projects? "Just one more small change, I'm sure it'll work after that"...suddenly it's 3am, the damn thing still doesn't run, I have a meeting at 9, and I hate myself.

All the time.

I once added a single logging statement to our code here thinking "what could go wrong" - turns out that triggered a logging email to get sent, which in turn delayed things slightly, which in turn created a race hazard that pulled the whole server over.
