Being smart and cheat shows how dumb we can be and deceive ourselves. Those people live in dormant minds which won’t go very far.
When you wake up to the potential of the fact that you are human, meaning you can learn new things and expand your skill horizon, why would cheat in exams and try being smart irresponsibly? The only reason I can think of is when we think little about ourselves.
Wake up to the genuineness of a genius heart.
