‘If we are washing dishes and thinking of others who are enjoying themselves doing nothing, we cannot enjoy washing the dishes. We may have a few clean dishes afterwards, but our happiness is smaller than one teaspoon. If however, we wash the dishes with a serene mind, our happiness will be boundless. This is already liberation.’ (Commentary on the Diamond Sutra)
Obviously, this does not just apply to washing dishes.
