When something works for you or another brand, ask yourself, 'Why?' Then don't copy it but think about what you can do that's unique to you and better.

The leverage and influence social media gives citizens are rapidly spreading into the business world.

It is time for corporate America to become 'the third pillar' of social change in our society, complementing the first two pillars of government and philanthropy. We need the entire private sector to begin committing itself not just to making profits, but to fulfilling higher and larger purposes by contributing to building a better world.

Define what your brand stands for, its core values and tone of voice, and then communicate consistently in those terms.

There are many individuals, companies and even countries operating in what I call a 'me first' mentality, which is effectively a purely competitive approach to life, treating the planet as if it has infinite resources and pitting one country against another for supremacy.
