I work for a small company (not a software/tech one) as a sysadmin and programmer and sometimes I feel almost ashamed of scripts or pieces of software because I know that they could be implemented much better or cleaner or this or that.

(I am currently reading "Coders at Work" and really enjoying it). Thanks for sharing!
