Life is not a bed of roses but a bed of thorns. It is full of dangers and difficulties. In the race of life, we should not be afraid of taking risks. Success in any work in life is achieved by people who welcome risk. Science would not have made such beautiful achievements if our scientists had not risked their lives and comforts. The more difficult work is the harder our efforts to perform it should be. Life is not smooth sailing. Little difficulties frighten a weak heart who is not prepared to take a risk. But brave souls achieve fame and honour because they enjoy taking risks. In short, risk brings success and performs miracles.
