You might be a big fish in a little pond
Doesn't mean you've won
'Cause along may come a bigger one

Coldplay - Lost! lyrics meaning

Meaning

Martin uses the idiom "Big fish in a small pond", which describes people who enjoy being important within a small group or organisation, but in the wider world have much less importance.

There's always a bigger fish, so it's best to keep your head screwed on straight, and keep doing what you do.
