It's not about.......

It's not about how many hours you practise your Tai chi every day, in the sense of forms.

You could be doing hours and hours of practise in some pseudo-masochistic disconnected ritual of delusion.

More important is the quality of your practise and being open to moments of insight and subsequent investigation. For example, build the frame ( standing ) then investigate moving the frame ( form ). What method, how to train, how do you move etc.

Let this percolate and permeate your life.
