This from Day 24 might be my favourite:

I wrote this because we have a choice. Actually, we have multiple choices. If we're being real, we have infinite choices at any given moment. We have an uncountable amount of choices. So many choices that we become aware of the rate limits of our minds. There is always one more choice that we haven't thought of yet. At least we think so. But do we know? There aren't many choices that we can think about at the same time. So by definition, at some point, we will have forgotten what we thought about before. So we're kind of stuck thinking about all the choices we have; never realizing that we have no choice but to think about the same choices over and over again. There are so many choices that we have to accept that our choices are limited to just a few since a few is all that we can think about. And when we don't think about it, we're back at thinking that we have a choice or worse: that we have no choice.
