Today was yesterday

Today was yesterday's tomorrow
Today will be tomorrow's yesterday
Yesterday's today was yesterday
Tomorrow's today is tomorrow
Yesterday's day after tomorrow is tomorrow
Tomorrow's day before yesterday was yesterday
The day before yesterday's tomorrow was yesterday
The day after tomorrow's yesterday is tomorrow
The day before yesterday's day after tomorrow
And the day after tomorrow's day before yesterday
Are both today
The day after tomorrow's tomorrow
And the day before yesterday's yesterday
Are both too far away
Todays turn into yesterdays
Tomorrow never comes
I think my tomorrow is today
Or maybe it was yesterday
Damn
I'm not sure which is which, anyway
So this is all I have left to say
Don't worry about the future
Don't turn your mind to the past
Just live this moment while it lasts
For far too soon it will also pass
And don't forget
Today's today is today
Where does all the time go?
