How long does it take to complete 23 things on a stick?

One of my co-workers asked me at our meeting last Wednesday, how long did it take to complete the 23 things on a stick. My answer to her was around 40 hours, plus. She looked at me a bit confused and I explained to her 23 things on a stick has no set amount of time. I worked about 40 hours to complete the program for the requirements, and have since added quit a few more hours to it. I explained it is a on going education tool, it gives you the basics, where you take it from there and how much you achieve with it is up to you. I have found it very valuable not only at work but also in my personal life.
