      Could you be a genius like Einstein? A genius needs to learn and think. Reading is a good idea, but it is not

enough. Einstein's advice is to use your brain more. Here are some tips:

      # Ask. When you look at new things, ask why they are new or different. Ask questions. Ask yourself and

ask others. Keep thinking until you find the answer.

      # Draw. Einstein thought in pictures. Sometimes, it helps to draw problems and ideas.

      # Read. Try to read new things. Read books from different parts of the library. After you read, think about

the ideas you have learned. Are they different from what you thought?

      # Relax. Many ideas come when you are relaxed. Take some time to relax yourself in the ways like taking

a walk in a park, going to a concert or a museum.

      # Write. Keep a diary. Write down your questions and ideas. Write down new ideas after you read.

      # Share. Einstein used to talk to his friends and explain his ideas. Sometimes, a friend can help you find the

answer to a problem.

they think you are wrong. Then decide.
