It's about love conquering all.
You can interpret it anyway that helps you make meaning of it to your life.
When your love reaches someone
No matter how hard it is, no matter how much you want to give up
Don’t ever stop believing
Carry on carry out
Even if you get a little tired of hurting someone and getting hurt
And the bittersweet feeling of being in love
Oh, try dreaming again
If you know the joy of being loved
We’ve come this far by making a wish
On each shooting star we see in the night sky
No matter how hard it is, no matter how much you want to give up
You’ve gotta believe that one day love will win
Carry on carry out
Longing for something, having it taken away, giving and being betrayed
Makes love grow
Oh, the further away something is
The greater the joy you surely feel when you win it
There’s nothing to worry about, there will surely come a day
When your courage reaches someone
No matter how hard it is, no matter how much you want to give up
You’ve gotta believe that one day love will win
You’ve gotta believe that one day love will win
