Favorite Quotes from the Mars Family 

“There are cases where government-to-government aid actually has worked. Look at the eradication of smallpox and the near-eradication of polio. But these are really top-down solutions that require government-to-government support and aid.” – Jacqueline Mars

“The poor don’t live in functional market economies as the rest of us do, but in political economies where corruption and broken systems extend from local government to moneylenders.” – Jacqueline Mars

“Despite the hundreds of non-governmental organizations and the continued outpouring of foreign aid, East Africa remains as a region overwhelmed by extreme poverty.” – Jacqueline Mars


3 Leadership Lessons from John Mars

Now that you know all about John Mars’ net worth, and how he achieved success; let’s take a look at some of the lessons we can learn from him: 


1. Talk Less, Listen More

People will pay attention to what you say, just because of your position.

The leader’s job is to pay attention to what other people say, especially those who think their views don’t count. Show you’re listening by acting on what people tell you, and gain their trust by giving them the credit.


2. Don’t Step In With Solutions Too Quickly

No-one learns anything new if you keep doing what you already know how to do, and don’t allow others to try. Anyway, they may find a different or better way, and if not… mistakes are valuable too.


3. Be Authentic

Be authentic, passionate, even emotional, about what you believe in. Share your vision and live your values. The personal is more engaging, even inspiring, than the process.
