There are three main groups of wood careers, the first type being those that are directly associated with wood and its products: jobs involving furniture and textiles, vegetarian restaurateurs, florists, fruit and vegetable vendors, perfumers, botanists and herbalists. Paper is derived from wood and accounts for the second main group of wood careers: paper/stationery makers and suppliers, publishers, administrators, writers, artists and other creative types. Traditionally, the qualities associated with wood are caring for and nurturing others, which leads to the third group of wood careers: social workers, counsellors, teachers, religious leaders, pharmacists and other medical occupations. In the cycle of birth, water nourishes wood. Thus, those in wood careers should have business cards in colours associated with water (black, navy and light blue) or wood (green). Colours to avoid include those of the metal element (white, grey, silver, gold) because metal is used to chop down wood. Fire colours (red, orange, purple, pink) are also not recommended. Don't panic if your doctor's card has a white background as this is usually combined with black lettering. White represents metal, which feeds into water (black), which then nourishes wood, representing medicine.
