Tomorrow never comes

Oh I'll do it tomorrow...

Tomorrow what do you mean?

Tomorrow does not exist just like the past.

When you put something off for tomorrow, and you reach tomorrow... but tomorrow becomes day after tomorrow.

"I'll do it tomorrow" is synonymous to "I will most likely never do it".

If anything can be done tomorrow that you are putting off, do it now.

Cheers... As to follow my principle I am going to study.
