Your life is created by your emotion and thoughts. The mind you have is more powerful than you think and imagination is more important than knowledge. People who are poor are still poor or the rich is still rich is because of the way we all think and what we do. If you hurt yourself and have negative thoughts that signal sends it out the atmosphere around you. Don't focus on the bad things focus on the things you should be grateful for then imagine the things you want and never let that go because it'll come to you somehow. We all have a bunch of thoughts running through our mind and we control them by our emotion those emotions tell us if it makes us feel bad or feel good, we want positive because it's more powerful than the negative. The things we conceive can be achieved. Everything within the universe is energy it cannot be destroyed only created in different forms. There is no such thing as too little but too much so we shouldn't worry so much about the world ending or anything. Stress is a bad emotion you shouldn't have like if you say disease it means a body not at ease. The world has so much bad emotion its causing problems not just by our action but our thoughts and what we hear.Many ways to start this is write down what you're grateful for and be positive. If you have troubles with someone think only about the good things about them because the more you complain the more things you don't want from that person just like you are with what you may want or don't have.If you stop changing then you might as well stop living because life is all about changes.
