I tried my best, but I failed. Else, I wouldn't be here.

You need to finish your homework by tonight, or else you won't be able to go out with your friends.

It's not my responsibility, it's somebody else's problem.

Who else is coming to the party?

His voice is like nothing else.

I saw someone else at the party.

If nothing else, at least this is certain.

Above all else, prioritize your health and well-being.
