Thanks for clarifying. That sounds like a useful game, but I wonder how much you would have to practise it before you saw concrete gains.

I'm very interested in techniques for having more and better ideas, because I think most of the good things I've done in my life have been directly due to having a new idea or insight.

A model for winning by rationality is:

• Decide on a goal.
• Come up with ideas for achieving this goal. (creativity)
• Identify the best idea or plan among those you've come up with. (epistemic rationality, general prediction ability)
• Execute the best plan/idea. (willpower)

If you lack any of these steps you will fail. I'm surprised at how little discussion I've seen on LW about coming up with more and better ideas.
