Owning things–even beautiful things–will not give you peace of mind. Consumer goods will not prevent the loss of people you love. New stuff will not shield you from feeling not good enough or attractive enough or successful enough. And expensive, status-focused toys will not make you a celebrity giddy with champagne.
What will give you peace of mind? I think you know: Love. Faith in something or Someone bigger than you. Making a difference by helping others. Doing something you really believe in. Spending quality time with people you love. Having experiences that open your mind, your imagination and your heart.
