Your first name of Petrock creates an idealistic, sensitive nature and a desire for culture and the refinements of life. A lack of positivity and confidence is a source of difficulty in making decisions in business dealings. A tendency to put on weight could be a concern. With training you could be artistically creative as you have an appreciation for music and the arts. The mysteries of life intrigue you, and you enjoy reading, especially about mystery, science fiction, or possibly the occult. You would work best in a relaxed environment at tasks involving writing, mathematical, or analytical skills that require concentration. Happiness and fulfilment are elusive under this name. The inclination to daydream needs to be curbed as it is detrimental to mental progress. Procrastination is a weakness, for so often you are inclined to avoid issues and to leave things undone until the last moment when you are forced to take action. The heart, lungs, or bronchial tubes could also be an area of potential weakness, with asthma, flu, or pleurisy ensuing.
