Peace- to me, it means low stress and low chaos. And when I have "peace" I feel like I'm better equipped to handle issues and negativity is reduced.

@Michael Clegg I'm sure that on some levels, having "peace" is actually learning how to respond to situations even when my surroundings aren't "peaceful." In stressful moments, thinking more clearly instead of "reacting." Also, focusing on what I can and cannot control.
