From the ISS Cupola reflecting on a life challenge I heard long ago – 'Be strong enough to know when you are weak... brave enough to face yourself when you are afraid... never substitute words for actions. Learn to stand up in the storm, but have compassion for those who fall. Always have a heart that is clean, a goal that is high... learn to laugh but never forget how to weep.' - Until we meet again...
