这是关于个人磁场的文章，后面提到了正面和负面情绪的影响，你可以参考一下
Personal magnetism is not something only attributed to people like movie stars or politicians. All of us possess our own brand of magnetism. On a very basic level, our bodies have own energy field, and, just like a magnet, we all can attract (or repel) people, situations or things either to or away from us.
This is because our thoughts and emotions are forms of energy as well, and the thoughts and emotions that we "send out" have a great deal to do with how others perceive us and how we interact in the world.
Changing our thoughts and getting clearer about our emotions has a direct affect on our energy. The key here is for us to become aware of the types of thoughts and emotions that we generally have. Are they positive and open to possibilities, or negative and critical (of yourself or others)? A simple point to remember is that we attract what we focus on. Try to check in throughout the day to see how you are feeling.
For example, if you catch yourself having a negative thought such as, "I'll never get ahead," you're sending out a negative, or repelling, energy. But if you can turn it into a more positive statement, like "I am tackling the challenges along my chosen path," you'll be sending out a positive, attracting energy.
So, boost your personal magnetism with positive thoughts, and, like the old folk song, "let your little light shine."

Is your habit to think positively or negatively?
What is your tendency? Are you more prone to look at your routine tasks as something you gotta do or something you get to do?
How we look at the way we spend our time has everything to do with our motivation toward it and the level of satisfaction we enjoy. If we don’t feel what we are doing is significant, then it won’t be.
Get into the good habit of training yourself to see these things in a positive light and you will be amazed at the difference it makes.
Making this a habit takes practice, but it is worth it
Developing a good habit takes awareness and some effort. You have to become conscious of when you have a wrong thought. When you do this, you will probably be amazed at how many times within a day that you stray from the kind of thinking that you desire. That’s okay! At first, cut yourself some slack. Starting to realize how you typically think is the first step toward curing yourself.
Of course, if all we do is recognize our mistakes without taking any action to correct ourselves, then we aren’t really going to improve. The next step is to start replacing our erroneous thinking with the kind of thoughts we desire.
When I catch myself, out of habit, thinking that I gotta do something, then I simply remind myself this isn’t something I have to do, but something I am choosing to do. I also state either aloud or in my head why I am making this choice.
It usually takes some time, but soon I find my thinking changes. I start instinctively thinking positively which is exactly the good habit I want to develop!
