Today's gonna' be the best day of my life, so far
Today's gonna' be the best day of my life, bye, bye
I've no particular reason why I think today's gonna be so nice
But today's gonna' be the best day of my life, so far

No, it's not my birthday or the end of school
And I didn't win the lottery or anything that cool
I didn't get a trophy for something great I've done
But, I say today's gonna be so great, it's only just because
(Just because) 
I feel like having the best day I can
And if you don't like it, well, I guess that's your problem

Today's gonna' be the best day of my life, so far
Today's gonna' be the best day of my life, bye, bye
I've no particular reason why I think today's gonna be so nice
But today's gonna' be the best day of my life, so far

Why would I need a reason to have an awesome day?
For me it's enough when I wake up to look around and say
"Hey! Today's gonna be the best day that I have ever had"
And I'm not quite sure if it's going to work but I'm gonna tell my dad
(Just because) 
I feel like having the best day I can
And if you don't like it, well, I guess that's your problem

Today's gonna' be the best day of my life, so far
Today's gonna' be the best day of my life, bye, bye
I've no particular reason why I think today's gonna be so nice
But today's gonna' be the best day of my life, so far

And if I fail to have the best day that I can
Then I'll wait for tomorrow and I'll try it once again
And again, and again, and again, and again
Again, again, again, again, again

Today's gonna' be the best day of my life, so far
Today's gonna' be the best day of my life, bye, bye
I've no particular reason why I think today's gonna be so nice
But today's gonna' be the best day of my life, so far

Today's gonna' be the best day of my life, so far
Today's gonna' be the best day of my life, bye, bye
I've no particular reason why I think today's gonna be so nice
But today's gonna' be the best day of my life, so far
Yeah
