What do you think makes an individual successful or unsuccessful?

Good
Honesty: Admit you don't know and be ready to learn. Give credit where it's due.
Integrity: Hard Right over the easy wrong
Praise in Public: When something goes right, don't take personal credit for it. Rarely ANYTHING in life is done by yourself so share the good times with those who were there to make them happen.
Bad
Attitude: If you don't have the right mind, right thought process you'll never succeed.
Close-mindedness : Refuse differing opinions. "My way or the highway". They might go first, but you'll be next.
Public Admonishment: If Praise is in public, punishment shouldn't be....but that isn't how it goes. It takes away morale, trust, and cohesion.

That depends how you measure success COL Mikel J. Burroughs.
If success is measured by fame and fortune then those born into wealth have a distinct advantage.
Thankfully real success is not measure by fame or fortune.
Helen Walton was incredibly rich yet she had a down to earth attitude because she had faith in Christ. "It's not what you gather, but what you scatter that tells what kind of life you have lived."

Awesome visual chart. Sir, let me think on your questions for a couple days.

1) The first positive trait (or thing as you describe it) I would say is a loving sense of Self Discipline. Meaning you don't beat yourself up, when you fail to accomplish a goal, but you get past the disappointment or anger stage quickly and analyze why you failed. Do you need more time to prepare or more resources (such as training or studying or external support form co-workers, or family and friends), to accomplish your goal? Loving Self Discipline seems to me to be at or near the top for very successful people, athletes, academicians, or creators/inventors.
2) Indefatigable Sense of Resilience coupled with a willingness to fail. They are inseparable, two sides of the same coin. You have to be willing to fail, and fail often, and yet remain optimistic and resilient in the face of set-backs. High achievers seems to have this almost supernatural ability to risk failure, eat up failure, and not be discouraged from achieving their goals. They really have inculcated the idea that every failure brings them one step closer to success or obtaining their goals. Thomas Edison has a famous quote that encapsulates this idea. Some are said to be born with this trait, or it was developed in them by life experiences, by their parents at an early age, but by the time of their adulthood, they have this trait for success deeply ingrained in them.
Thanks for sharing this inspirational post, Sir.
