How can we improve our reality now?

It seems like we often take knowing things for granted even when what we think that we know is predicated on many assumptions. Perhaps if we take a step back, and 1) become okay with not knowing, and 2) become okay with knowing that much of the way we think and or act is at best misguided, and at worst wrong, then we can make progress. We need to dig down to get to some semblance of bedrock where we can begin to build a house. This bedrock will be very small, as that is how much of reality we perceive. From there, we can create a stable structure of thought and belief, knowing well the limitations that we have imparted due to our assumptions. We must keep in mind that no matter what we do, most of our reality will, in the end, be based on assumptions, and we will, therefore, remain in the domain of not knowing.
