Consistency in Kung Fu training, no matter the style, is an absolute must.  But rather than going on about all the pros and cons of the subject, let me explain it in the form of a story that was often told by Grand Master Cheng:

Once many years in the past, there was a very famous old Kung Fu master who knew his time had come.  So he called his three oldest students to his bedside to tell them the greatest secret of Kung Fu.  He bid the eldest of the three to kneel down close, and with his last ounce of chi, whispered the secret into the student’s ear.  And right after that he died.

The eldest student sat upright with a combined look of amusement at what he’d been told and deep sadness over his good teacher’s passing. The other two student’s had a combined look of sadness and great anticipation over what the greatest secret of Kung Fu was.

“Well!”  they finally blurted out, “tell us, what was Master’s secret?!”

The oldest student looked blindly at them and said, “Keep Training!”
