You enjoy thinking about all manner of things thoroughly — be it a decision, a design, or a premise, it's all worth pondering. But you have too much zest to sit still with those thoughts. Once you've had time to process, it's time for action! Take care, however. Some people see this as officious. Try to express your enthusiasm in a way that doesn't come across as demanding.
At work, you prefer something that exercises mental muscles, but just theory isn't enough. As with personal musing, you won't be content until you can manifest those concepts in reality, or at least make progress in that direction. One warning: your independent nature means you might either rush what can't be rushed, or set out alone even when you know you need help.
That hurried nature comes out in relationships too. You fall in love very quickly, and expect your feelings to be returned. The wisdom and balance of the birth number 2 may come to the rescue here, helping to pace interactions.
