I’ve been thinking a lot lately about the habits and knowledge in your life that you don’t realize are arbitrary. All the things you “know” or do because that’s just what you were told or the example you had to follow and then never really thought about again. For example, you can just eat the whole dang apple. It doesn’t really have a core and the seeds can’t hurt you unless you eat a huge number of them, so you are wasting a whole bunch of apple if you eat around the center, fibrous bit and throw that away.
