Well, I believe these words came from
The Pokémon movie

Every single morning, I feel the same way
My dreams are always better than my days
Remember what you told me, I gotta stay strong
I don't think you were wrong

And not that you'd care
But I started getting the help that I so badly need
And not that you'd care
But I found some people who really like me
But I hope that you do
'Cause I started bettering me, 'cause I wanted to be like you
Oh

I started bettering me 'cause I wanted to be like you
I started bettering me 'cause I wanted to be like you
Now you're no better than me, and I've got nothing left to prove
I started bettering me 'cause I wanted to be like you
