Either you connect what you have to learn to what you want to do, or it's not important. At the end of the day you are either curious about most anything to see how it works, or not, and it's something that can be built. If you're looking for the motivation to be curious, find something you're already curious about and interested in, see what algorithms might be at work in it, and see if it ties back to the book.
Motivation isn't some magical discovery that carries you through the rest of your days. Motivation is a daily bath to remind yourself of what's important to you and why. Forget to bathe your mind and feelings and they'll stink and seem worth staying away from.
