To Be And Not To Be

Be a wheel,
Don't be a cog.
Be a stream,
But not a log.
Be a factor,
Not a pawn
Be a comer -
Not a gone.
Be a something,
Not a dud.
Be a blossom,
Not a bud.
Be a figure,
Not a blank.
Be a motor,
Not a crank.
Be a worker,
Not a drone.
Be the meat,
But not the bone.
Be the real thing,
Not a dummy.
Be alive
And not a mummy.
