Unchecked desire is a never ending quest to attain an always bigger boat. Ironically, once our needs are met, having more is not found in acquisition, but rather in deciding that you would like the peace of mind in not dealing with the consequences of pursuing further material acquisition. At some point, for all of us, contentment is the greatest thing we can acquire.
But do not confuse contentment with complacency. Contentment is not complacency in accepting poverty. Contentment necessitates the rejection of poverty. Knowing what is enough means knowing what isn’t enough. Contentment is the rational understanding that you have all you need to be abundantly happy, and deciding that further happiness is the liberation from unfathomable desire.
