Someone once said: In this world, we often forget our own jobs but tend to care more about other people's stuff. So, why not just take care of your jobs and let God do the rest.
The destiny is what we have sown in the past, what we are doing now and all will influence the future. What we should do is to make it clear who you are, what your position is, how to react appropriately to the world in order to free our minds. If you cannot put a step into the other's world, leave it! You don't need to try to intervene, making it difficult for either them and you.
This book shows you a painting of world, where the rules of nature should be respected. This could help us to be in peace yet observe the world.
