Be Zen but Don't be a Chump

Does the saying, ‘Let go and Let God’ give you great comfort but you have difficulty fully implementing this philosophy into your world? Perhaps a slightly different saying might work for you. In Dan Harris’ excellent book “10% Happier”, he cites an Ancient Arab Phrase: “Praise Allah but tie your camel”.  He goes on to elaborate in his own words, “Do what you can to ensure a favorable outcome and then let go.  Or, be zen but don’t be a chump.”  In what ways can you do the legwork and then let go today?
