You define the contours of your character and the shape of your life by what you say “no” to. For example, saying no to invitations is the way you safeguard the attention you need to say yes to what matters most. Saying no to demands that compromise your values is how you secure your hold on those values. Articulating your reservations about a proposal is the work of acquainting yourself with your own thoughts. Expressing disagreement with an exuberant crowd is the very sacrament of personal integrity. A sculptor creates a masterpiece from stone by subtracting the pieces that don’t belong. By the same token, it is what remains after removing those things you decline that becomes who you are.
