A ship is safe in the harbor, but that is not what ships are built for.
I taught high school in the early 80’s. I had this quote hanging on my classroom wall in one of those inspirational-type posters with a sailboat setting out to sea. I suppose I was trying to inspire my students to reach for adventure as they launched themselves into the world. I still draw inspiration from these words every time I am faced with the choice of a challenge and an adventure or playing it safe.
