Life gives us a lot of knowledge of cause and effect that is useful for us to survive and adapt to anything that happens in nature that makes us as humans have to use that knowledge to survive and adapt. So that humans like us will not fade away with the times that continue, we must believe in ourselves that life can make us humans who have many interests that are needed by other humans.
Likewise, good things continue to come to us, without us realizing that every thing that comes to us when we realize it or not we realize it often brings good things that make us better, so we need to occasionally look more closely at the things that come to our lives, sometimes these good things come at a time when we don't like and don't like it even though it is a good thing that comes to us when we need it.
