1, One of your classmate is not good at speaking what can you advise her to do for improving?

Eat a healthy diet

A healthy diet is good for your brain. Eat fruits, vegetables and whole grains. Choose low-fat protein sources, such as fish, beans and skinless poultry. What you drink also counts. Too much alcohol can lead to confusion and memory loss.
7. Manage chronic health problems
Follow your health care provider's advice for dealing with medical conditions, such as high blood pressure, diabetes, depression, hearing loss and obesity. The better you take care of yourself, the better your memory is likely to be. Regularly review the medicines you take with your health care provider. Some medicines can affect memory.
64. Can you tell the difference between motivation and inspiration?
For years I thought that inspiration and motivation meant the same thing. But the more I thought about it, did some research, and became a student of people, the more I came to believe there’s a very important distinction. The subtle difference between the words can make a world of difference in leading people.
Merriam-Webster defines inspiration as follows: “Something that makes someone want to do something or that gives someone an idea about what to do or create.”
Here’s what it says for motivation: “The act or process of giving someone a reason for doing something.”
Inspiration is more a person reaching a point of wanting to act, whereas, motivation is more of giving people reasons to act. That’s the difference between babysitting and empowerment, incentives or influence, fire-starters and fire extinguishers.
There is a need for both inspiration and motivation. But to lead effectively, knowing the difference makes a tremendous difference.
When we try to motivate people by using positive incentives, and perhaps even some negative tactics, that’s using outward things to enter the heart where real change takes place. This can work to some degree but the effect is often temporary.
When we try to inspire people, we’re reaching for the heart in a way that the person is changed from the inside out. When people want to change because there has been a deep stirring in their heart, it’s sustainable and leads to long-term vibrancy.
There was a time in my life when I consistently sought encouragement from others as my main source of motivation. Sometimes I’d get it, other times I wouldn’t. I needed the encouragement to perform well.
Then I began to be inspired by a purpose-driven challenge in my life, as well as some individuals who helped me understand that what I do should not define who I am. This changed everything.
With motivation, I was looking for reasons to be a better me to maximize performance. With inspiration, I understood who I was and, as a natural byproduct, I was able to accomplish things that I never thought were possible.
