Few things in life are as inevitable as taxes. ... But taxes aren't limited to the funds we pay the government to keep itself running. Sometimes we levy heavy taxes on ourselves. When we make ourselves keep paying and paying for some mistake, when we expect perfection, when we are unwilling to forgive our failures, we pay a higher tax for being human than anyone, even God, expects. We all have a price to pay for being human, but we don't have to become self-extortionists, expecting more of ourselves than we can possibly pay.
