In a conversation, Nod and smile and give backchannel responses that make it seem like I do, and wait until the person speaking says something I do understand, to give context to everything before it, and then make an educated guess to what they were talking about.

In IT, look up every word in the man page I don't understand, and then every word in the definitions of those words, and so on, until I understand the basics of the systems and protocols underlying what I am working on, and then build back up from there.

In life, play something like a holy fool [0], and accept that things don't need to make sense for me to be okay.[1] Also that the sense that things don't make sense, could just be a feeling made by trying to cling to a framework of knowledge that is showing its limitations, and needs to be expanded or left behind. Also know that my sleep, diet, physical activity, all play a big role in my sense of mental clarity, and try to keep to good habits.

As a human being, get away from other human beings, into someplace green and let direct observation of the billions of years in the making natural world, and my self as a natural thing make all the sense that is needed.
