One important trait gamers have is what Jane McGonigal calls "urgent optimism".
It's an optimism that drives the person to tackle obstacles, regardless of their difficulty.
And they don't give up, attempting to overcome the obstacles over and over again. Should they realise that they are not ready for these obstacles, they actively seek out new skills and undergo training. They have a clear goal in their mind, unfettered by any failures.
On the other hand, in real life, how many companies would see a failed project and just scrap them? How many have been put down by society who is only good at saying "I told you so"?
