Ever heard the phrase that success is 20% knowledge and 80% psychology?
Given that the 80/20 rule tends to bear out in most cases, continuing to gather knowledge won't make you successful - what's more important is the self-belief that you're capable and deserving of massive success. And that's where most of us fall down.
Knowledge without focused determination is useless. It's why so many talented and gifted people have ended up destitute and penniless. Without the drive and confidence to achieve, knowledge is quite literally useless.
