Your time goes to whoever asks the loudest unless you decide who gets it first.
STILLNESS
STILLNESS
Time that is not claimed in advance gets taken by whoever is most insistent, which has nothing to do with what matters to you. Urgent requests arrive with volume attached, and important things usually arrive quietly, so the quiet ones lose by default. Deciding first is the only real defence.
Choose two things this week that get your hours before anybody asks for them. Write them down so that saying no has something behind it.
