I suspect most users of Unix-like systems make a mistake of that 
category once. Hopefully once is enough to teach the value of backups 
and being careful. I made that mistake once on a production web server. 
And then had an enjoyable evening of learning how to use a hex editor on 
a filesystem, followed the next day by setting up automated backups.

A practice i've developed (especially when logged in as root) is when i 
want to do an "rm -rf" to first do an "ls -d" with the same file 
argument to confirm that i have the file correct, then edit the previous 
command to swap ls -d with rm -rf.
