In business, things change. 

One day you’re fighting your competitor in the streets, next day you’re collaborating with your competitor to lobby government to unban alcohol sales. 

No matter how bitter the enmity, remember: things change. 

When the financial incentives provide for alliance, your enemy will be your ally.

So don’t get personal or emotional. 

Don’t say things you’ll regret.

Today’s enemy is tomorrow’s ally.
