This exercise will demonstrate how important it is to draw your ideas, as opposed to simply writing them down.

Get out a piece of paper and draw a picture of a shoe. Make sure to draw in all the details such as the logo, laces, treads, etc.

Now, write a paragraph describing in detail every piece of your picture. Imagine that you are having a telephone conversation with an alien who has no idea what a shoe is. You might start with something like this, "This item is about 10 inches by 3 inches by 4 inches. The bottom is made of rubber and is in the shape of a..."

Which part of this exercise was easier? You probably found that it was very difficult to describe certain shapes or aspects that were easy to draw. Do you think the drawing or the text would more quickly convey the idea of a shoe to an alien?

Flow is a mental state that was first described by psychologist Mihaly Csikszentmihalyi. It is characterized by the ability of creative people to block out all distractions and fully immerse themselves in an activity. When someone feels like they are "in the zone" or "in a groove", it is likely that they are experiencing flow.

The unbroken concentration that comes from flow can be refreshing and invigorating. Extreme productivity and highly creative ideas are often the result of a flow experience. People come out of flow feeling happy and fulfilled.

Someone who is experiencing flow may lose their feeling of self-awareness. They will become completely absorbed by the activity and forget about themselves, sometimes ignoring bodily needs, such as eating and sleeping. They may also become unaware of the passage of time and may be surprised when they realize how much time has passed while they were enjoying the activity.

Unfortunately, it is not possible to get into flow on command, but it is possible to shift things in your favor. Reducing disturbances is very important. Each phone call, instant message or other distraction call pull you out of the flow experience. It is also important that the task you are working on posses most of these criteria:

1. The person must have active control over the task.
2. The task must have clear goals and expectations.
3. The task must give immediate feedback, such that mistakes can be quickly corrected.
4. The task must not be so easy that it is boring, but not so difficult that it is frustrating.
5. The activity should be intrinsically rewarding so that participation is its own reward.

To learn more about flow, you can read Mihaly Csikszentmihalyi's book "Flow" at Amazon.com.

Caffeine is probably the most commonly used chemical stimulant. More than 90% of Americans consume caffeine on a daily basis in their coffee, soda, tea, or chocolate. Pure caffeine is a white bitter-tasting powder that can be extracted from coffee, tea, the guarana berry, or from other sources.

Caffeine is a brain stimulant. It works in the brain by blocking the natural effect of adenosine on the nerve cells, causing increased mental activity. It also causes the body to release adrenaline, which causes the heart to beat faster, blood pressure to rise, muscles to tighten up, and extra sugar to be released into the bloodstream for a burst of energy. This is why it is often used to counteract sleepiness.

Caffeine is an addictive substance. When the effects from caffeine wear off, the feelings of fatigue, depression, and irritability set in. Taking more caffeine can counteract these feelings, but this leads to a dangerous cycle. With prolonged use, it can interfere with the brain's ability to reach deep sleep and become fully rested, which means that the person will feel tired in the morning and be more inclined to take even more caffeine.
