How much is enough?

"Now everyday ain’t gona be no picnic
Love ain’t no walk in the park
All you can do is make the best of it now
Can’t be afraid of the dark

Just know that you’re not in this thing alone
There’s always a place in me that you can call home
Whenever you feel like we’re growing apart
Let’s just go back back back back back to the start, oh

Anything that’s worth having
Is sure enough worth fighting for
Quittings out of the question
When it gets tough gotta fight some more"
