First off, it's important to understand a vision board. A vision board helps you put in visual form the aims you have for your life. So let's say your quest is to organize your office. Your vision board might be all about the ideal type of office you would want. It would incorporate magazine photos, drawings, words, and whatever else calls to you. By hanging that on your wall and focusing on it, it helps keep your progress on path to achieve that goal.
So now we incorporate the feng shui angle into this. Most vision boards take their words, images, and photos and stick them onto a cardboard sheet in a way that is more artistic than planned. Things just go wherever they fit. Feng Shui will help you put them where they make more sense.
Your aim is to put particular items into their proper spot on the following grid:
Not every vision board you make will directly connect to all of these areas, but often by thinking outside the box you can see how various areas relate to the topics. For example, with your office organization project, having a more ergonomic chair could help with your health. Taking on more long distance clients could help expand your ability to travel.
Give a feng shui vision board a try, and tweak them as they go!
