n+1. Consider a gambler. He walks into a casino and has a good run at the tables. His 1000 turns into 10000. The success was so easy; surely it can be done again. A funny thing happens. You're up 6000 now, but 6000 is a lot less than the 10000 from earlier. Now 6000 (6x your starting money) _seems_ like a fraction of what you _could_ win. It's the human adaptability problem. It's also an ego problem. The next success should be bigger than the last one, or it's not exciting. And since you were so good that you 10x-d your money earlier, surely you can something-x your money again. Now consider the conservative (limited?) mind. You walk in with 1000. You win 150. You go home, because you've gained 15%!!! (You never 10x your money. You never get a million.) So that's the problem. The mind that knows when to stop stops so early that it never achieves something extra-ordinary.
