"Honesty first, then courage, then brains, and all are indispensable" Theodore Roosevelt

Honesty, courage and brains are essential and indispensable.
Honesty helps in developing good attributes like kindness, discipline, truthfulness, moral and integrity. Courage gives you the ability to put aside your fear of failure and take the first steps. Someone with courage is bold and brave, unafraid to face tough challenges. Intelligence is the ability to think, to learn from experience, to solve problems, and to adapt to new situations. The combination of excellence.
