As I read, Napoleon Hill's insights are indeed revealing.

They remind me of this beautiful quote from internationally acclaimed accelerated business growth strategist Jay Abraham:

"As soon as you open your mind to doing things differently, the doors of opportunity practically fly off their hinges."

He adds:

"You are surrounded by simple, obvious solutions that can dramatically increase your power, influence and success. The problem is, you just don't see them."

Internationally acclaimed creativity guru Dr Edward de Bono shares his sentiment, for he says:

"If you wait for opportunities to occur, you will be one of the crowd... Opportunity ideas do not lie around waiting to be discovered. Such ideas need to be produced."

Even world renowned brand strategist Erich Joachimsthaler has similar thoughts:

"Opportunities for innovation and growth are right here, in fact, in front of us, and we often can't see them or don't act on them."

To cut to the chase, we just need to sharpen our perceptual sensitivity.
