By being so certain of ourselves when there is no legitimate basis for our certainty, we miss out on layers of intricacy and understanding. Maybe we even injure ourselves. Making assumptions, thinking we're above the need for help, directions, guidance, etc, is a dangerous place to be. It invites disaster. If we don't right-size ourselves, the universe will do it for us.
Let's be ok with needing help and instruction, with not knowing, and not understanding. If we must assume, let's begin with the assumption that we don't know everything, and that we likely need to start slowly and ask for help. That is the place to begin, and the one that will insure our ultimate success.
I can be a beginner at things. I'm not afraid to ask questions and seek direction. I don't need to be an expert right away.
