Martial arts in marital life

Master Yoda (illustration
If you weren't born with a gift to lie, get married. You'll become Master Yoda sooner than it takes you to master yodeling. 

(to master yodeling, it only takes you a pair of cogwheels and a little imprudence)

Thou shalt not stop practising marital arts for all your life. For the opponent practices too!

The previous commandment does not imply that the opponent is embodied in one single persona.
