I've made that statement to myself and anyone who was listening many times over the years.

Just recently, I was struggling and frustrated trying to get the toolbar I built in my RoboHelp project to publish correctly.  No matter what I tried, I just could not get it to look the way I wanted it to.

I expressed my frustration to a graphics designer on my team and after showing her a few things, she knew exactly what needed to be done and with no more than a quick "tweak" of my image she had everything fixed.  And she doesn't even know a thing about RoboHelp!
It's not what you know, it's who you know.

Asking for help can be humbling
As an instructor, we're expected to know everything.  Provide answers to student questions "on the fly" with confidence and without error.  Luckily, as social media and user communities have grown, the age of one person knowing all the answers isn't as expected any more.  If you don't know the answer, you know someone who does.  Just tap into your tribe of experts or share a link to an on-line resource for the answer.
