Start by taking a friend by hand or arm and walk with him in a crowded place like a grocery store or a busy street and your job is to avoid hitting your partner into any person or object. Change places and work this drill closing first the eye you shoot less with (guns, balls …) and than the later.
Repeat the drill but now have your partner face the other way and close his eyes so you have to read his tension so you can guide him without getting tensed and rooted in one spot.

Later on you can work with a few partners on a group settings in a more pressure type of work and remember all the implications of your work.

Tips: Keep breathing, relax the spine, avoid getting into a mission oriented frame of mind and just do the work. Being a hero is a good recipe for a story but a bad one for a long life. Keep movement to what works and avoid other movements.
