My Chinese zodiac animal is the Horse - I was born on the 11th of January so I'm a Horse while others born in 1991 are Goats.

Well, let's see...

strength, energy, and an outgoing nature
I  have no strength whatsoever, no energy and I'm not outgoing, not at all.

extremely intelligent
Some people say I am, some people say I'm not. However I know I am capable of thinking more abstractly than others; I easily get a hold of different philosophies. My intelligence is linguistic and philosophic.

they don’t always finish what they start
This is sooooo true!

honest, friendly and open-minded
I am honest and open-minded but I really can't describe myself as friendly. I am selfish and mean.

a bit too centered on themselves and have been known to throw tantrums when situations don’t go their way
A bit? Haha.

very healthy - - a positive outlook on life - - athletic
Doesn't fit at all - I get sick easily, I am negative as Hell and I'm not athletic.

positions in which they can interact with others
Umm, no thank you? No interaction with people, please!

publicist, sales representative, journalist, language instructor, translator, bartender, performer, tour operator, librarian or pilot
PERFORMER? Hell no.

a tendency to fall fast and hard for others
I think I just recognized myself.

give themselves fully in each new relationship
Yes. Yes. YES.

And I am a Metal Horse which is described as free-spirited. Commitment is the easiest way to scare Metal Horses away. They prefer jumping from one relationship or job to the next. Because of this, Metal Horses make better friends than partners.
I haven't been scared away even though I'm engaged. Hooray.
