I totally agree with moodster here. All the people I've met who I've regarded at being are the best at they do (be that programming, sysadmin work, dba etc.) are all really humble and quite ready to admit there is loads they don't know. In fact I'm always a little bit dubious about people who are arrogant about their prowess - surely nobody is that good?

On that note I constantly amazed about the amount of stuff out there to learn that would be applicable to my work. This morning for example I'm having to read RFC 2257 (which deals with Mail Agents Extensibility) because I want to make sure my MIME::Lite app will work. But this means there are at least another 2256 RFC's dealing with all manner of things that would probably benefit me to know. How terrifing is that? Then there are the myriad of perldocs, unix administration docs, Linux kernal books to read..... gulp

I'm be hiding under my desk from now on, whimpering...
