jwz quote that's stuck with me

I could have benefitted from internalizing this quote when I was starting out, I was one of the skittish ones.:

"I think that's one thing that's really important is not to be afraid of your own ignorance. If you don't understand how something works, ask someone who does. A lot of people are skittish about that. And that doesn't help anybody.  Not knowing something doesn't mean you're dumb--it means you don't know it yet." --jwz (from Coders At Work)
