I was educated to think maybe Brazil works, maybe it doesn't. But I decided I am going to make this country work for my children. I am investing all my effort now in making Brazil a great country.

Don't think you are unstoppable or foolproof. Don't think that the only way your business will work is through perfection. Don't aim for perfection. Aim for success.

Don’t aim for perfection, aim for success.
