I'm trying to find a quotation part of which includes the word "horizon". The gist of the quotation is fixing one's eyes on the horizon rather than looking down.
"Never look down to test the ground before taking your next step; only he who keeps his eye fixed on the far horizon will find the right road."
The above is a quote from Dag Hammarskj�ld, Secretary-General of the United Nations from 1953 - 1961.
Is that the one you are looking for?
