Shannon Lee, Bruce Lee's daughter, was sharing an excerpt from her father's Daytimer from 1969.  I want to share it with you because I think Bruce Lee is one of the most insightful person for his time.  His words are always full of thought.   Each word possesses a lot of weight in its meaning and its deliverance is with a lot of enlightenment.  I love to read his poems.  They are very, very wise words.  See for yourself:

From Bruce Lee:
To-Day
"Look to this day, for it is Life.
The very life of life.
Within its brief span lies all the verities and realities of your existence. 
The Bliss of Growth.
The Glory of Action. 
The splendor of Beauty.
For yesterday is but a dream and tomorrow is but a vision.
But today well lived makes every yesterday a dream of happiness and every tomorrow a vision of hope.
Look well therefore to this day.
