Yesterday was gone
Whatever we did yesterday has been a thing of the past
We can't do anything with it
Tomorrow is something uncertain
We don't know whether we will see the sunrise tomorrow
What we all have is today
Even then, we don't know whether we will live until the next hour
Or for that matter, the next minute.
Actually, what we have is the puff of fresh air that we breath in at the very moment
So, make good each puff of fresh air that we breath in now, the next one and the next....
Until our lung collapse
