walk the line

the desert is a most treacherous environment... as deceiving as the camel that walks its dunes. for a camel does not show signs of fatigue... it may appear that you can work a camel relentlesly and it will just do as ordered. it will keep on walking and will never seem to tire or wear. but beware... because once driven to exhaustion, it will just drop and shut down. the horse is not like that... it will show its limits and you will know only up to how much you can ask of it and when to let it rest.
