Many people who come to tai chi are very eager to achieve the smooth flowing movements - myself included when I started out.

However, it's best just to practise getting the weighting on the feet/legs right first, because if the arms are smoothly flowing and the feet/legs are all wrong, you're not actually achieving anything - the whole body needs to be moving as one unit.

So take your time to get the feet and legs feeling right with the proper weighting, before you get concerned about smoothly flowing. The smoothness and flowingness will come with time and practise, after which you will be ready to start learning about how to add the internal aspects into your tai chi. Be patient and you will allow the process to happen!
