Example: "We cherish them with all we have and that makes us care about it so much that it is really precious to you." Repetitive and badly structures. Poor grammar. When you write "We cherish them", you have to follow up with a pluralised subject as well (If you don't know what I mean, please look it up." So, "We cherish THEM with all we have and that makes us care about THEM..." rather than "care about it." You can't go from "Them" to "it." One is plural, one is singular, you see? You can't mix that.
Also, once you establish that someone cherishes something, there is no need to call that something precious within the same sentence, or even paragraph. Those things mean the same thing.
Lastly, you have confused your own message. Your first sentence states the important things in life aren't things, but people. Then you say people love things more than people, sometimes...
