Practical thinking

Mostly, we think things following the one in front of us. This means that our thoughts are expanded from some seed, which is in our mind. This is to say, thinking based of nothing, sometimes this ability is called "the imagination", is absolutely difficult.

We rely on the things almost exist, and as a result, there are so many similar things.

Of course, abstraction from actual things is sometimes required ability, and congestion is too. These two process is the way of accelerating things; especially thinking. Sometimes this is called knowledge management.

But referring something is different from making the same things without thinking of the basic purpose of sone action.

There are so many knowledge that others have experienced, and we can enjoy them with little effort. But as the knowledge increases, it comes to be more important to recognize the base point of the things.
