I think the 5th point, "Don't be afraid to Ask", is an excellent one. Technically, just about every Perl related question could be answered by diligently seeking out the answer in documentation, quickly in my case
, but sometimes not so quickly. It just depends and how clear the documentation is on whatever you're having problems with. Documentation is mostly written by humans and its not perfect, and the people who write them are certainly not psychic - which would be especially bad for those of us who dance naked in front of our house pets (they're our pets for Christ's sake, it doesn't count, right?) ... but it's not like I do that or anything.
My real point is that if you're starting CGI progamming, the more and more you try at solving your problems the easier it gets and question asking is a necessary part of the learning process, as well as exercising your manual reading skills.
