My first knowledge of QuickBooks was with the current company I'm in. She started the company from the ground up and I was there from the very beginning and I helped her learn, the owner, learn QuickBooks and that's how I learned QuickBooks as well. A lot of YouTube videos call us to QuickBooks, but I am the sole QuickBooks manager at the company I work for, so I'm really the only one that's in that position, so I think I know QuickBooks pretty well.
