Once you make up your mind to do a particular task and you set yourself on the path, there is very little that can distract or dissuade you from completing your mission. You are willing to work extremely hard to achieve your goals, and your focus, endurance, and stamina are incredible. The intensity of purpose that you demonstrate demands respect and sometimes instills fear in others.
You overcome obstacles that would defeat most people. To you, they are opportunities to become stronger. You know that the best results are often not immediate, so you're not attached to instant gratification, which gives you a great deal of patience and willingness to wait for the right moment. You are protective and suspicious, carefully guarding your work and your secrets, and you never reveal absolutely everything to anyone. There is a part of you that is extremely private and reserved. Oh -- and obsessive. Stubborn. Dogmatic. And don't forget passionate! You get the picture, and it's likely no surprise to you. These qualities are part of what ensures your success. You earn it yourself and you don't want to share it. If there's one thing you hate, it's wasted work: You really want your efforts to count for something worthwhile.
