Common problems (and how to fix?)

I've gotten into the habit of pressing ctrl-s ALL the time. I've lost hours of work too many times.

I guess one of my problems is getting everything done in a day that I want to or in the middle of working on something having to switch to something else to take care or this or that problem. But that's just all part of work and I expect it now. You just have to try and do as much as you can without killing yourself...at least that's how I look at it.
