For about 5 minutes Sunday night I thought I had lost all of my data from the last field season. This was particularly bowel-twisting given that I thought I'd lost it both from its original home and the back-up CD. There was cursing, there was crying, and even though it was found in the end, it was real enough that it took me a good 2 hours to fully calm down. I just kept seeing my committee, and tried to think of some plausible reason for having nothing from that time period. Like I said, humiliation is a very strong motivator.
To re-assure myself, today I saved the data to the lab computer. There can not possibly be too many ways or places to save this! There is also a copy under my mattress. It is lumpy.
