If you can't be a pine on the top of the hill

   Be a scrub in the valley --but be the best little scrub by the side of rill

Be a bush , if you can't be a tree

  If you can't be a bush ,be a bit of the grass

And some highway happier make

  If you can'be a muskie ,then just be a bass

But the liveliest bassin the lake

 We can't all be captains ,We've got to be crew

There's something for all of us here

  There is big work to do and there is lesser to do

And  the task we must do is the near 

  If you can't be a highway ,then just be a trail

If you can't be the sun , be a star

  It isn't  by size that you win or you fall

Be the best of whatever you are !
