++Grandfather for some great suggestions.

Let me add a couple of my own ...

Use Data::Dumper whenever you're in doubt what your data looks like.

Ask short questions in the Chatterbox -- people are often quick to give great advice there.

Experiment with new concepts, and they'll quickly become part of your repertoire.

Use a debugger of your choice.  My personal favorites are print and printf. ;-)

Treat others the way you'd like to be treated.

Share your own knowledge and experience; everyone has unique gifts to offer.

Have as much fun as you can.  The journey is at least as important as the destination.

Good luck!
