Good advice/observation. Reminds me remotely of Did you talk to the bear? - found here: brian's Guide to Solving Any Perl Problem.

Did you talk to the bear?

Explain your problem aloud. Actually say the words.

For a couple of years I had the pleasure of working with a really good programmer who could solve almost anything. When I got really stuck I would walk over to his desk and start to explain my problem. Usually I didn't make it past the third sentence without saying ``Never mind---I got it''. He almost never missed either.

Since you will probably need to do this so much, I recommend some sort of plush toy to act as your Perl therapist so you do not annoy your colleagues. I have a small bear that sits on my desk and I explain problems to him. My wife does not even pay attention when I talk to myself anymore.
