Relax, breath gently, zanshin, moving with center, extend ki. You can do this all the time and it will help with your practice regardless what style you do.
As Ahmad said, and I would add the basic tenets of Jigoro Kano, the founder of Kodokan Judo, Seiryoku Zenyo (Best use of Energy) and Jita Kyoei (Mutual Benefit). If we do these things with strong, but relaxed zanshin, always trying to improve every day our practice will develop into maturity. This place, right now, is the dojo.
