Wake up, it's a beautiful day
Get up, get up, get up, get up
Get dressed, I'm feeling great
Put on my make up and my hair

My day just begun
Gonna make it a good one
Gonna do what I want to do
Gonna make it a great one

I'm gonna go out and play
Take a walk in the park today
Find some flowers and some butterflies
I'm gonna have the time of my life
Chorus:
My day just begun
Gonna make it a good one
Gonna do what I want to do
Gonna make it a great one
Bridge:
Oh, yeah, you know I'm gonna make it happen
Take my life and make it count
Make every moment, every second count
Every single second of my day

My day just begun
Gonna make it a good one
Gonna do what I want to do
Gonna make it a great one (x2)
