adele's new album

Hello,
Can anyone explain to me what "chasing pavements" mean? (maybe "chasing rainbows"?)

to chase rainbows means to waste your time trying to get or achieve something impossible.

And I found this about "chasing pavements" on the internet:
- it is about not even having anything to chase... so you are just chasing pavements
- to keep pursuing something even if you know that to keep following it, you may not get anywhere at all
- Adele describes ‘Chasing Pavements’ as “It’s me being hopeful for a relationship that’s very much over. The sort of relationship you hate when you’re in it, but miss when you’re not”.

Hope that helps although I am not a native English speaker.
