Make this your daily objectives ! No need to wait for the yearly / quarterly national conference or Town Hall gathering. Very simple, in daily behaviors sharing vision means also STARTING WITH THE END IN MIND, eg saying :
we will have closed this project /
make this decision /
sign this contract,
we will be in the position of… /
then xyz will be possible/
then you’ll be able to… “
So WHEN…. THEN.., that’s the formula for sharing what you see and envisage for the future.
