The most common mistake is to take Feng Shui too seriously! I have all too often seen awkwardly placed furniture and strange 'lucky' objects like crystals, or frog statues placed all around a space. This not only does not work, but sometimes actually makes the situation worse or impedes in the flow. Other mistakes I have seen happening in a living room is positioning all the chairs to face the TV, or using the wrong size of furniture which messes up the scale.
