This is a good article on the art of letting go. What I like best is the constructive suggestions to re-frame situations that can trap us into cycles where we serve everyone but ourselves.
One good example is being unwilling to shut your door to get work done because you want to have an open door policy. Though that philosophy is a good one, it is not an absolute. Good managers have an open door policy and good managers sometimes shut their doors to get the job done.
She has other good suggestions in the article related to not saying yes everytime something is requested and how not to fall into the “I’ll just do it myself” trap. Worth checking it out.
