Your mind never stops working. It's difficult for you to turn off your thinking, no matter what you are doing. Mental discipline could be difficult for you to develop because your mind is an independent agent, doing what it wants, and it could be a challenge to coordinate your mental processes with the rest of you.
You use lists to keep yourself organized. Nervous energy may be quite a problem for you, a nervousness that can be remedied by meditation or yoga. You may actually become well known for your mental prowess but in truth you may feel misunderstood a lot of the time. Others can't keep up with your mental speed, and may misconstrue or misinterpret what you say. You won't be on the same plane as many others intellectually, and it will be difficult to bridge the gap. On the other hand, you are quite an independent thinker and aren't restrained by what others write or say about your ideas. You're also not held back by past or present ideas that may not jive with what you're currently thinking.
