[Chorus:] Today's gonna' be the best day of my life... so far! Today's gonna' be the best day of my life... so far! 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, then I guess that's your problem [Chorus] Why do I need a reason to have an awesome day? For me it's enough when I wake up and 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'll try the best I can Just because I feel like having the best day I can And if you don't like it, then I guess that's your problem [Chorus] And if I fail to have the best day that I can Then I'll wait for tomorrow and try it once again And again, and again, and again, and again Again! Again! Again! Again! Again! [Chorus x2]
