In all the hustle and bustle, noise, talk, booming, rattle, pounding and sounding, try to maintain that calm. Among the rat-a-tat-tat and horns blaring, keep that quiet thing going. If you got it going inside, then nothing from the outside can come in and throw a giant rock into your calm waters and cause a splash and ripples that overflow your banks and flood you with negativity. Keep it nice and steady; maintain course and glide along like a song, marching to your own beat and marching to where you want to march. All that other crap is just extraneous clutter that gets in the way.
