hinokata: first, welcome.
taijiquan is a wonderful martial art and well worth the time it takes to learn. it has extremely good health benefits, and can be very effective for self defense as well. i would have to agree with bamboo leaf in that you have to "empty your cup" when you are starting taiji. (or anything else for that matter!) if you are limited to training with someone in your local area, then find who you feel is the best, and learn all you can from him or her. also study the taiji classics--these are the writings of some of the past masters about the principles and theory of taijiquan. they should be readily available in books. what style of taiji are you learning? yang? chen? wu? sun? they all have different flavors and shapes, but the principles of the art should be the same throughout. i will tell you one good thing that has held true for me as i enter my tenth year of practice: the more i learn, the deeper it gets, and the more i want to know!
and i'd like to reiterate something that you've probably heard ad nauseam, but bears repeating: there are many crap versions of taijiquan being taught these days--don't let that discourage you from looking thru all that to find the good stuff.
