You know, according to science, a bumblebee should never fly because its body is heavy and its wings are small.
According to all the disadvantages of aerodynamics, it should fall to the ground. But still, it flies because it doesn't believe in any law or theory; it believes in itself.
And this teaches us one thing: people's opinions and the world's theories don't define you. You define yourself. People's downfall begins when they start doubting themselves.
It's a simple law of nature: those who try move forward. Those who stop remain behind. Remember, what the world thinks of you has no value. The results of your work define your value. So, believe in yourself, not in people.
