What we need is to ask the questions again. E.g. why do I need work on a new language? If the answer this time is different, even slightly different, that is because after a certain amount of effort, we accumulated experience and gained additional knowledge, and we have become better at what we do (relative to the question, e.g. programming). We are inherently very arrogant, often assume a God-like attitude, that once we had an answer, that is the answer. That is a trap that we do not really benefit from. What we needed is a scientific attitude, that we don't have the ultimate answer (to anything), so we need investigate the same questions again and again, while reminding ourselves, that every time we reach a slightly different answer, we have become better selves.
