Hard question! It's a bit like: what is the feeling of doing right piano or doing wrong piano?
If you were learning the piano, you would not expect to play perfectly hard pieces in a month. First, you learn the fingering for right hand, then left hand, then you learn how to play them together. First slowly, then faster, then more complex pieces, .... After a few years, you can play the same pieces with much less effort.
Taiji can be a bit overwhelming in the beginning. Take it easy!
Each time you do the form, concentrate on one single thing at a time. One time the shoulders, one time the footwork, another time relaxing the kua, another time the breathing, etc. After a few months, it should start feeling a bit easier. Little by little, you will see other details in the form, and you will work to incorporate them in your form.
Taiji is an effective martial art, but the martial training happens as we work on the HEALTH part. Relaxing is most important, and as Isabelle said, the best feeling of doing Taiji right is when you feel happy and in a good mood after a class or practising the form.
Oh, that piano analogy reminds me of something Franz Listz (I think) said about learning piano: the muscle memory builds faster when we go slow.
One more thing: in Taiji, the upper body and the kua are relaxed, but the legs will get sore, even in a high posture.
Hope that helps. Tell us how it goes!
