身体健康需要补充维他命，精神健康也要补充“心灵维他命”。你是自己思想的产物！用英语说就是“You are what you feed your mind”或者“You are what you think”。
One of the most important habits in life is to feed your mind with positive mental food. Remember, you are very susceptible to the suggested influences in your environment, whether radio, television, newspapers, magazines, billboards or conversations with other people. Your mind is your most important and precious asset. You must protect it and keep it clean, clear and focused on what you want, rather than allowing it to be polluted by the negative influences around you.
Refuse to watch terror or trash on television. Refuse to read about all the murders, robberies, rapes and tragedies in the newspapers. Refuse to listen to endless hours of mindless radio commentary on all the problems in the modern world. Refuse to engage in endless conversations with people about all the political and social problems in your nation or community. Keep your mind clean, clear, positive and free.
Not only do you become what you think about, but also you become what you feed into your mind on a regular basis. If you want to be positive, optimistic and happy, continually feed your mind with positive books and articles, positive audio learning programs, positive input and information from other experts in your field, and positive conversations with other optimistic goal-oriented people who are going somewhere with their lives.
