As food is to the body, so is learning to the mind.
Our bodies grow and muscles develop with the intake of adequate nutritious food.
Likewise, we should keep learning day by day to maintain our keen mental power and expand our intellectual capacity.
Constant learning supplies us with inexhaustible fuel for driving us to sharpen our power of reasoning, analysis, and judgment.
Learning incessantly is the surest way to keep pace with the times in the information age, and an infallible warrant of success in times of uncertainty.Sample Output Copy
