well some words that come to my head

Negative

"Wherever there is darkness , there is light"

Because

For light to exist there should be darkness and without darkness light and dark will be the same

"Whoever hates someone/something and is still alive , surely loves someone/something"

Because

Without feeling love/hate no one would ever experience the other as both the feelings would be same for that half-dead individual and he will be emotion less and above all lonely

"Wherever there are loosers
there are winners"

As without looses the winners won't be winners and winners and loosers will be same and we should always support both winners and loosers
As if you don't support winners they will eventually fall and loosers will loose there will i.e.
They will become half dead
