Practical Dreamers never quit

Yet again, I heard a line in a podcast that I had to re-wind and listen to twice so that I would make sure to remember it.

"Practical dreamers never quit"

I think I'm going to paint this on a plaque and hang it in my studio.
This line is from Napolean Hill's Think and Grow Rich. I don't know if it is a direct quote because I am listening to it on audiobook. I was running when I heard this line and once I returned home, I jumped on eBay and found a Buy It Now to purchase a copy of the physical book.
Can't wait to read it even though I've already heard it.
