It isn’t the thing you are doing,
But the way that you do it, my friend;
Not the course, but the way of pursuing,
On which your successes depend.
There are prizes in every vocation,
And he is the fortunate man
Who frets not, because of his station,
But does just the best that he can.
—True Worth Wins: Lillie Sheldon
In this theatre of man’s life, it is reserved only
for God and angels to be lookers-on.
