I’m a fiction writer, but this can apply to most of us.
In the middle of getting my first mystery (One, Two – Kill a Few) published and working with my editor on the second in the mystery series, my desktop computer came up DOA.
I have an external ( 1 tb) hard drive I use for backups. It was a pain in the tush to pull files from that external drive and use them on my 10″ screen net book. At least it kept me alive in the real world.
