By enjoying the success of others, you effectively align your personal vibration with that which you desire. If you find the achievements others have obtained to be desirable, and you admire them and you feel good about them, you are effectively aligning yourself to be harmonized with those achievements and you will actually begin to move towards the fulfillment of those achievements in your own life.
On the other hand, if you were to resist the success of others, your focus would be placed upon lower and slower vibrations that do not make you feel good. By simply accepting the success of others, and even celebrating it as your own, you can move into alignment with the vibration of success to find success for yourself.
Not only is it more enjoyable to be happy for those who are successful, but it is also good for you on a vibrational level. Everything in the Universe is vibrating at a specific frequency. As you focus your attention on various subjects each day, you are setting the personal vibration you currently maintain. If you are feeling good by focusing on good feeling subjects, you will continue to feel good. If you are feeling good, but then you put your attention upon bad feeling subjects, you are going to start feeling less than good as a result.
The fact that you begin to vibrate in harmony with success when appreciating the success of others can be harnessed in a variety of ways. As you continue to harness the power of appreciating success obtained by others, you will continue to bring your personal vibration into alignment with very high, pure, and fast moving frequencies that will bring success into your life.
You attract experiences that are similar to the vibration you are currently emitting. The vibration you are currently emitting is the way you feel. When you feel great, you are attracting experiences that will make you feel great. If you do not feel great, you are then attracting experiences that are in alignment with you not feeling so great.
For this reason, you should do your best to always align yourself with good feeling thoughts to create good feeling experiences for yourself. When you appreciate the success of others, and you feel good while doing so, you will quickly start vibrating at a good feeling frequency that will attract more success into your life. The more attention you give to good feeling experiences, the better your current life experience will become as well.
In summary, as you give your attention to good feeling thoughts, you are attracting good feeling experiences into your life. The better those thoughts feel as you are thinking them, the stronger the attraction between yourself and that of good feeling life experiences will become.
