Be the change you want to see

यद्यदाचरति श्रेष्ठः
तत्तदेवेतरो जनः ।
स यत्प्रमाणं कुरुते
लोकस्तदनुवर्तते ॥

– भगवद्गीता

Whatever a great person does, other people imitate the same thing. Whatever standards he sets up, the world follows the same.

Be the change you want to see in the world.
The best example of leadership is leadership by example.
