If we have a goal in life, work becomes like mountaineering. We have a view of the role we want to play: a vision of becoming a complete person, contributing both as an individual and one of humankind. One stands at the foot of the mountain and the climb seems easy; yet after the first few hours it becomes difficult, you get tired, you rest, then the path clears only to get difficult again before the summit — but what joy and what ecstasy on reaching the top where the canopy of Heaven is all-embracing.
