This one is sung in The Land Before Time XXIV: The Incredible Journey after Littlefoot's banishment for life from the Great Valley. He confesses to Rooter that he feels like a failure and that he loves Ali but isn't sure how their relationship will work out now. It is similar to How Do You Know? from The Land Before Time XIII: The Wisdom of Friends in tune.
Littlefoot: Sometimes you think you know what's right
Then somebody comes along
and they show you what you thought was right
might be a little bit wrong
Things can look so different
from someone else's side
You're half as smart as you thought you were
and the world seems twice as wide
How do you know who to listen to?
how do you know what to think?
When you see it through someone else's eyes
things can change in a blink
Do you hold onto the rules you've learned?
or do you let them go?
When everything's a muddle
how do you know?
Rooter: You only have to do your best.
You cannot control what happens with the rest.
Sometimes things don't go the way you want them to go.
If you follow your heart, then you will know.
(In the Great Valley)
Ali: Sometimes things go a way that you wish wasn't so.
You feel like you've been dealt a very hard blow.
The circumstances lead one way and your heart another and you're not sure where to go.
You wonder and wonder, how do you know.
(Back at the Great Divide)
Littlefoot: My mother said she'd always be with me.
Even if her I couldn't see.
Ali and I seemed meant to be.
I wish I could see through this pain and woe.
I wish I could figure out how do I know.
