Today.
What is today's purpose?
Why are we here today?
Today is a chance
A chance to change
A chance to be better than yesterday
Yesterday
The past is yesterday
Who we once were is yesterday
The mistakes we have committed are yesterday
But not today
Today we learn
Today we grow
We Prepare for tomorrow
Tomorrow is the future
Tomorrow is unpredictable
Tomorrow is a culmination of of what happened yesterday
There is no Today without yesterday and and what happened yesterday will change tomorrow.
