How to Release Creativity
According to most dictionaries. creativity is the ability to create. However, creativity is more than what is defined by the dictionary. It is an idea, a process, a thought。or a state of mind. One cannot learn to be creative because creativity is natural and unique to each individual. People should know that creativity doesn’t equal success. It equals the act of expressing. So. if at first the goal that is aimed for is not achieved, there is no need for worry or frustration.
Creativity can, however, be released by discovery. Some people need encouragement to help
release their creativity. There are quite a few ways to release it.
One way to release creativity would be to look for what can inspire you. Looking at the world and admiring the differences in people and places help. Creativity can be drawn from their beauty. A person can touch, taste, smell, hear, and see hundreds of different objects. Aromas from foods, textures of blankets, and sight of unusual objects can all give inspiration.
Many people are too concerned with how things should look. The focus should be on how it actually looks in the raw, to the human eye. Colors and shapes can be distorted(扭曲)by the mere fact that people want others to see it for what it is. It’s more difficult for someone to let go of all that and just let their creativity flow, unblocked.
Another way to get the creativity flowing is to research what other artists have done or are currently doing. Their cultures and biographies alone can be an inspiration. Examining their works can help some appreciate artistic expression. New techniques can even be drawn from their works.
Some people are even inspired by everyday events, like reading the newspaper or watching the news. Some can take other people’s situations and describe how it makes them feel. That is a way to release creativity. Controversial issues, such as War or abortion, can inspire writings like poems. They can be used to express death, loss, or tragedy. General topics such as religion or politics can branch off into many directions, sending creativity into overdrive.
Creativity is not about reaching a goal or being a perfectionist. It’s about being, feeling, and taking all that is inside and letting it out in one way or another. Creativity is not always expressed by paintings, drawings, or writings. One’s action is the main form to express creativity. Romance, for example, is a form of creativity. Love and emotion are inspired by one person for another. Taking something inside and then putting it back out into the world as another thing is the key of creativity. Knowing and loving someone so much that there is a need to express it is a very natural form of creativity.
Another form of expressing creativity is talking. Some people are more blessed in this area than in more obvious ones。such as painting or drawing. They Paint a “word picture”. Speeches can be centered around new ideas and thoughts. It can contain an of one’s being and transform it into either simple or complicated words.
Inspiration is vital to creativity. Even if it’s only a slight feeling or thought that inspires. Creativity can be released each time attempts are made to use the body as all outlet. Remember that creativity is not an art form, but that it forms art.

American is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while—then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time.Sometimes , we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine (常规). They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!
