The first time I heard the phrase "university on wheels" from one of America's top business speakers - Brian Tracy, I didn't get it, until I reasoned through what he was really saying.
Brian was talking about the incredible amount of information we can absorb while listening to professional and educational audio books during your drive to and from work.
You see, many people "waste" up to 2 hours or some even more every single day commuting to work and back. During this time they may listen to some songs or do nothing other than hum to themselves. Their minds are in neutral all of the way to work.
Now... consider this pleasant, yet startling fact -
If you listen to the right professional audio books each and every morning as you commute to work you will hear the equivalent of a full university education within a few years!
Here is how this works.
You see, for some university degree programs, students spend no more than 10 hours weekly attending their lectures. And after a few years they are given their degrees.
And what do they do during these 10 hours each week?
That's right - they "listen" to lectures!
You can get the exact same value from just listening to the right audiobooks in whatever field or area of expertise you want to learn about.
