Thoughts are steered in different ways.

Our heads are round so thought can change direction

With vertical thinking one may look for different approaches until one finds a promising one. With lateral thinking one goes on generating as many approaches as one can even after one has found a promising one. With vertical thinking one is trying to select the best approach but with lateral thinking one is generating different approaches for the sake of generating them.

Lateral thinking... is the process of using information to bring about creativity and insight restructuring. Lateral thinking can be learned, practised and used. It is possible to acquire skill in it just as it is possible to acquire skill in mathematics.

The two ways of contemplation are not unlike the two ways of action commonly spoken of by the ancients: the one plain and smooth in the beginning, and in the end impassable; the other rough and troublesome in the entrance, but after a while fair and even. So it is in contemplation: If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts he shall end in certainties.

The mind can go either direction under stress — toward positive or toward negative:

Lateral thinking is closely related to insight, creativity and humour. All four processes have the same basis. But whereas insight, creativity and humour can only be prayed for, lateral thinking is a more deliberate process. It is as definite a way of using the mind as logical thinking — but a very different way.

Rightness is what matters in vertical thinking. Richness is what matters in lateral thinking. Vertical thinking selects a pathway by excluding other pathways. Lateral thinking does not select but seeks to open up other pathways. With vertical thinking one selects the most promising approach to a problem, the best way of looking at a situation. With lateral thinking one generates as many alternative approaches as one can.

All the materials of thinking are derived either from our outward senses or from our inward feelings: all that the mind and will do is to mix and combine these materials.

With one eye you are looking at the outside world, while with the other you are looking within yourself.

Be more intentional about the direction we allow our minds to go. Meaning, when you catch yourself thinking negatively, STOP. REDIRECT to something positive.

Vertical thinking is selection by exclusion. One works within a frame of reference and throws out what is not relevant. With lateral thinking one realizes that a pattern cannot be restructured from within itself but only as the result of some outside influence. So one welcomes outside influences for their provocative action. The more irrelevant such influences are the more chance there is of altering the established pattern. To look only for things that are relevant means perpetuating the current pattern.

The thinking of the mind is twofold: understanding and willing.

The old linear pattern of thinking by reading and describing from left to right, top to bottom has many problems in organizing information coming from eyes, ears, etc. For example, the ability to read and understand the context of a book is different from memorizing them simply as sentences.
