About failure and success

I'm in the tube, London's underground and I'm listening to 'All Power - Nashville Life Music.' For the last few weeks I've been thinking about a subject that bugs me: the power of failure.

I've always been obsessed by the concept of 'constructive complaint' which is when you have an argument with someone, and your facted logic helps the subject realise his faults, and he gets motivated to change his behaviour and has enough 'self-fuel' to deliver positive response over a long period of time.

When you've failed in all, you've seen them all. Nothing is a mistery to you. Success is very clear in your mind and you know what you're looking for. But having enough mental or physical power to wait for the good part can be challenging, as it's hard to keep a positive attitude to failure.

I'm curious what was the internal dialogue in Edison's mind when he failed over and over again, 1000 times. What was he telling himself to keep himself going? After failing so many times, he probably started considering himself a failure, but he didn't give up.

Mount Everest is covered in corpses that once were highly motivated people. What is the turning point in someone's mind that allows them to carry on and believe that nothing can stand against their success?
What can compare to achieving your dreams?
But what happens after you become 'perfect'? One could swim in arrogance and look down on those around him. On yesterday's  Metro newspaper there was an article about a laywer that spent almost £3mil for his birthday party...  Almost £3000000! On the same page, just under this one, it was an article about couple that every Sunday prepare 300 meals for the homeless. They started with their own money, couple of years ago, and now people are helping them with donations. Which one you think is happiest and sleeps better at night?

We fail to see the big picture because we're focused on ourselves.
We fail in choosing the right one to follow and we rebel 'the system', searching for an utopic independence.
We fail to understand that pain strenghtens, it makes everything be real and we believe that the Universe has forsaken us everytime we have it rought.
We fail to understand what others are going through.
We fail in beong role models to our future generations. They won't be able to look up to us.
