A Black Belt is a white belt who refused to give up.
This can be true to anything you do in life. All successful people who succeed almost always refuse to give up.
No challenges or obstacles in their way will break them. They find ways to go over, around, under, or through to achieve their goals.
A Black Belt is a state of mind. It’s a state of being. It’s not what you wear around your waist. Using attributes like integrity, courtesy, perseverance, loyalty, self control, indomitable spirit, kind heart, strong will, intelligence, and so forth.
