Everything has a reason, nothing happens without a reason. Few of the reasons we realize with our limited minds, and many of them remain unknown, known only to God, even if we think in a moment of arrogance that we have realized them. In this ever-changing world, there are only a few facts, in contrast to many hypotheses, and the eternal problem of man is that he is often hasty in transforming hypotheses into facts, until the moment comes when he discovers the error of his beliefs, and then submits to the reality, and admits the shortcomings of his understanding, and the limitations. Realize it. In order to live happily in your life, you must have a lot of flexibility. You must accept the idea of making a mistake, admit it, study its causes, and try to avoid it in the future.
