完整的歌詞如下：
Yesterday, I was a dreamer with no goals,
Living my life for fun, without any rules.
But today, I have a clear goal in mind,
And I'm working hard to achieve it every day.
Yesterday, I was a person who couldn't make up his mind,
Living in the past, always looking back.
But today, I'm a person who's moving forward,
Looking towards the future, never giving up.
Yesterday was a dream, but today is reality,
Yesterday was a failure, but today is a new start.
Believe in yourself, never give up,
Yesterday was gone, but today is here.
