There will always be more that we don’t know than what we do know. Furthermore, of all the things we do know, can we say with confidence that we know them all equally to their deepest level of understanding? Probably not! So why then do we allow ourselves to feel overwhelmed and stressed about what we don’t know or aren’t good at? Learning something new is always the surface of its worth. Whatever it is has value that is up to us to determine by how much time and effort we choose to dig into understanding it. That is knowledge. All else is a good memory disguised as knowledge.
