Passionnnnate.

"The passions are like fire, useful in a thousand ways and dangerous only in one, through their excess." - Christian Nestell Bovee.

Above explains one of my favorite concepts: self control vs. passion. The idea of finding a balance between what ones passionate about and staying within the perimeters of ones moral judgement. Passion is toxic. It is in the midst of passion that people lose themselves. Its only when we submit to our passions that we can consequently sacrifice our sense, in a sense. Think about it. The cliche "heat of the moment" between over hormonal teenagers wouldn't exist if this was not true... Terrible example.
So, it is finding a balance of passion within a permeter or reason.

"Reason sits firm and holds the reins, and she will not let the feelings burst away and hurry her to wild chasms. The passions may rage furiously, like true heathens, as they are; and the desires may imagine all sorts of vain things: but judgement shall still have the last word in every argument, and the casting vote in every decision." - Pg. 189, Charlotte Bronte, Jane Eyre.
