I don't know what the following in red means. And what does "one" refer to?
You constantly study what works in whatever you read, see, hear, and do... You file the example on the shelves of your brain. You let your brain make new combinations of elements that your consider acting on but don't seem strong enough to inspire you to do them. And then one does, and you're on your way.
One "combination of elements" that moves you to action.
