We are bound to be great if we choose so and desire. We have to overcome adversity. You start with yourself. Acknowledge in yourself what's good and what's not so good. In everything we do in life, it's people that make a difference.
People are the key to life.
Make your friends people you can trust, people with integrity, people you can give your keys to, people you can leave your kids with, people with honor. Deal with people you can count on as members of your family. Deal with human beings in a respectful, honest, loving way. That's the meaning of life. If you can learn someone's heart, you'll never make a bad decision about that person again.
