Your first name of Sylvanus has created a practical, patient, scientific nature able to concentrate on the finer details of a project or undertaking. You restrict your association to a few and usually they are people who understand your independent, quiet personality. Quiet and determined, you enjoy activities on your own close to nature or with natural elements such as in floral design, gardening, fishing, oceanography, or farming. You enjoy learning from discussions, but express your deeper thoughts and feelings better through writing. Your endurance and persistence enable you to carry your activities through to completion. As you think in a methodical way, you could be quite inventive along practical or technical lines and would enjoy working with your hands in such activities as crafting or cooking. You would find enjoyment and peace in an outdoor environment studying the flora and fauna of nature from a scientific point of view. Lack of proper verbal and emotional expression creates intensity and unhappiness within you, which in turn disturbs your nervous system and depletes your vitality. You could express your thoughts more easily in writing than in speaking. You seldom experience the peace of mind that comes with composed thinking and emotional control.
