It’s not being of service to say ‘yes’ to everything you’re asked by the people you consider to be your customers. Especially if you have any discernment, expertise or wisdom to offer them.
‘Yes’ to everything turns you into an automaton, with no capacity to choose.
Soon you’ll be overwhelmed with requests that you can’t fulfil without running yourself into the ground.
And you’ll be left with no capacity to bring what only you can see, that they could never have asked you for.
