Your first name of Sinisterp has given you a quick, active mind, which has caused you to delve into many different ideas and theories. Thus your success in your undertakings is limited. You will not tolerate situations where your independence is curtailed or where you are being criticized. Though you can work on any undertaking intently as long as it absorbs your interest, you cannot persevere when confronted by obstacles or by tedious monotony. You will never tolerate a situation where your independence and individuality are curtailed. Where you have difficulty is in organizing and systematizing the handling of your responsibilities. You enjoy unexpected opportunities for meeting people, or doing things on the spur of the moment. You tend to do to excess whatever you like to do, until boredom sets in. You find it difficult to relax until you reach the point of exhaustion. Your intensity must have a constructive outlet; otherwise, pent-up repression and frustration could lead to uncontrolled emotional indulgences and experiences which could bring nervous indigestion, ulcerated stomach, or moods of depression with very morbid, destructive thoughts.
