I am not that far in the sequences, but these are posts I would expect to come into play during Major Life Decisions. These are ordered by my perceived relevance and accompanied with a cool quote. (The quotes are not replacements for the whole article, however. If the connection isn't obvious feel free to skim the article again.)

To do better, ask yourself straight out: If I saw that there was a superior alternative to my current policy, would I be glad in the depths of my heart, or would I feel a tiny flash of reluctance before I let go? If the answers are "no" and "yes", beware that you may not have searched for a Third Alternative. ~ The Third Alternative

The moral is that the decision to terminate a search procedure (temporarily or permanently) is, like the search procedure itself, subject to bias and hidden motives. You should suspect motivated stopping when you close off search, after coming to a comfortable conclusion, and yet there's a lot of fast cheap evidence you haven't gathered yet - Web sites you could visit, counter-counter arguments you could consider, or you haven't closed your eyes for five minutes by the clock trying to think of a better option. You should suspect motivated continuation when some evidence is leaning in a way you don't like, but you decide that more evidence is needed - expensive evidence that you know you can't gather anytime soon, as opposed to something you're going to look up on Google in 30 minutes - before you'll have to do anything uncomfortable. ~ Motivated Stopping and Continuation

I suspect that a more powerful (and more difficult) method is to hold off on thinking of an answer. To suspend, draw out, that tiny moment when we can't yet guess what our answer will be; thus giving our intelligence a longer time in which to act. ~ Hold Off On Proposing Solutions

"Rationality" is the forward flow that gathers evidence, weighs it, and outputs a conclusion. [...] "Rationalization" is a backward flow from conclusion to selected evidence.
~ Rationalization

Your effectiveness as a rationalist is determined by whichever algorithm actually writes the bottom line of your thoughts. If your car makes metallic squealing noises when you brake, and you aren't willing to face up to the financial cost of getting your brakes replaced, you can decide to look for reasons why your car might not need fixing. ~ The Bottom Line

Hope that helps.
