Simplicity means centering in on that which is important and letting go of the rest. It can mean living with few possessions and entanglements, but more broadly it is an attitude, an approach to life.
Simplicity allows us to consume less. It differentiates needs from wants and places a priority on the needs of others over our own wants. It also allows us to accomplish more of what really matters. When we approach a task or conversation with an attitude of simplicity we strive to keep ourselves focused on the essential core rather than getting lost in a clutter of distractions and embellishments. We listen for the same in the words of other people. Simplicity helps us to maintain clarity of mind and purpose.
