This is a great post full of low investment methods with potentially high payoffs.

Yet, I find the structure of this post to be personally hilarious! My favorite technique/provocation is not listed: randomly matching successful systems(or their principles) into new pairs. While effective, this notion is commonly rejected- that a new combination of old ideas/principles is not new, unworthy of respect, and furthermore can be considered criminal behavior(a violation of intellectual ownership). I find the absence here understandable and even defensible- but the irony of starting the post with a quote from Harry Potter and the Methods of Rationality is too much.
