Knowledge (1)
In this fast changing world, knowledge is updating every minute. To keep up with the world we have to retrieve ourselves with the latest news. It's like travelling upstream; if you are not going forward, you are going back.
This is what knowledge is all about: you have to keep it rolling. Apply what you learn in your daily life, using English to communicate, the knowledge learnt in Chemistry to help you buy detergent, the knowledge learnt in Biology to plant your trees, and the knowledge learnt in Physics to understand what is going on in NASA. And knowledge is as important as it can be. A bright future (your career) depends on the extent to which your knowledge is explored.
So, roll your knowledge from the earth to the sky, roll your knowledge from the textbook to the internet, roll your knowledge from the toilet to the cafe. Knowledge is something bizarre! But it is the key to the prosperous future and admiration. Make sure you are travelling upstream now!
