Your first name of Pieterse gives you an independent, serious, reticent, and studious nature. You are very conscientious and competent in all that you do. In fact, others find it challenging to understand you as you do not reveal your innermost thoughts unless you are completely comfortable in your friendships. Aside from these points, this name contains many fine qualities. This name does not offer naturalness of expression, and as it is too serious an influence, it should be changed. You can express your thoughts best in writing, and you express your appreciation of others through little acts of service rather than verbally. You do not express yourself spontaneously when conversing with others; hence other people may often regard you as being aloof, and even unfriendly. It is only when you are among people who understand your deeper nature that you can really be yourself. Physically, any weaknesses in your health would centre in the heart, lungs, or bronchial organs. It has created separateness from others and loneliness in your life.
