Let them that would build castles in the air
Vault thither, without step or stair,
Instead of feet to climb, take wings to fly,
And think their turret’s top the sky.
But let me lay all my foundations deep.
And learn, before I run, to creep.
Who digs through rocks to lay his ground-works low
May in good time build high, and sure, though slow.
