How will I fare in water snake 2013

Well, generally speaking, it is a fortunate year for you. So job changing can be ok. However, I suggest you think twice before changing a job 'cause you may achieve great in your current position in 2013 if you try harder.
As for wealth, it is not suggested to make large investment. Otherwise, you may have a loss.
It can be good to travel outside, but you need to be more careful to prevent the unexcepted accidents.
I'm afraid you may be too busy to spend much time with your partner. So my suggestion is never be too concentrated on your career to desolate your partner. In addition, mroe communication is also necessary for you two.
In most cases, your health will be fine, but you'd better avoid something adventurous and dangerous.
