there are two male elements, fire and air and two female elements, earth and water. thus a person on this cusp has equal parts male and female astrological energy, this person would more than likely be better able than the ordinary person to see things from both a male and female perspective.

This is a very interesting observation because this person would not have thought this about herself.  This person grew up with six brothers and was one of the boys... very tomboy-ish.  When playing the childish game Truth or Dare, she would invariably choose: DARE, because the boys respected that over revealing truths.  Over the years,  this person has had more male friends than female friends... 

fire is excitability and water is emotion, thus this person might have the tendency to have firey excitable emotions, maybe they anger quickly, but also let go of that anger quickly.

LOL  Gosh, you are good, dude!  This person is a very passionate in her emotions.  She doesn't just cry... she weeps.  She doesn't just laugh, she guffaws... Nothing is mediocre, it's taken to the hilt...  She does have a temper, she'll admit.  She's not afraid to state exactly what she's thinking or feeling if someone is brave enough to ask her.

this person probably has sustained passions, they are able to remain steady in their passions and pursuits. they don't run here and there poking their nose into various interests but not staying long, no they have passions and keep at them and keep at them.

Yes, this person is likened as very passionate.  She has projects and causes in which she's thoroughly involved, sometimes to her detriment.  This person is one of those people who do not give up, but continues going until the very end even if it takes years.  And this trait, at times, exhausts those around her mostly because they have given up already.

they may appreciate and cultivate an air of mystery (fire and water make mist, mist is 2/3 of mystery)

Yes, she much prefers intrigue than to reveal all.  But this observation is very interesting because she would not have considered this aspect until it was revealed.

they are probably good at making their way through fog, whether it is actual fog or the fog of mental confusions and theories and concepts. others may say "oh there are just too many conflicting theories, i can't make up my mind, i am just ready to give up" but not this one, they confidently navigate through all that bs to find the truth. but then they want someone to come and hide the truth so they can play the game again.

This person is very decisive oriented.  Often can see all sides to the problem with a workable solution right away and tries to begin implementing the solution immediately.  Yes, this drives people batty sometimes, but on the flip side, alot of people come to her for help about various things.  She thrives on researching and finding answers, whether it is about a specific person, a theory or theories.  When the answer(s) is found she  sometimes feels a little let down that the journey is over and she immediately searches out another truth or truths to uncover.
