Salutation to the dawn

While reading Dale Carnegie's "How to stop worrying and start living" I came across this poem by Kalidasa and wanted to share it:

Look to this day! 
For it is life, the very life of life. 
In its brief course 
Lie all the verities and realities of your existence: 
The bliss of growth; 
The glory of action; 
The splendor of achievement; 
For yesterday is but a dream, 
And tomorrow is only a vision; 
But today, well lived, makes every yesterday 
a dream of happiness, 
And every tomorrow a vision of hope.
