It's harder to change human nature than to change rivers and mountains

Everybody has different characteristics, preferences, goals of lives from their childhood. A person lives in their own world and he creates and makes his life good or bad. He is like a painter of it. When you want to say and change life of someone it is a stupid idea because people do not listen to advise of other people and have their own opinion. That's why changing human nature is very difficult and you better not do it. As for nature changing I can say that nowadays you can easily find impact of people in different nature ways - mountains, rivers, waterfalls and other things. That's why better change something around you than people.
