Consistency is the key to clear thinking. Aristotle described the principles of logical reasoning already in the year 345 B.C. Twenty four centuries later, his conclusions remain applicable. Entities should be defined on the basis of their essential characteristics. Actions lead to consequences. Today's events are the result of previous occurrences. Those few principles govern reality.

When a man formulates his long-term objectives, he should strive to write them clearly and break them down into simple steps. A comprehensive philosophy that cannot be summarized into a few sentences is of little practical use.

Ambitious goals require sustained effort, often over a period of decades. Reducing complex strategies to simple formulas motivates us to attain intermediate targets. Happiness is the result of preceding actions that generate slow incremental progress. Sharp thinkers look, at the same time, far into the future and close into the present.

There is no way of escaping the requirement of clarity. Talking about forthcoming achievements becomes irrelevant if we are unable to define what we need to do today. The feasibility of long-term ambitions depends on man's ability to reduce them to sequential steps.

Mistakes arise from the temptation to move too fast towards our objectives. Disorganized ventures fall prey to their own chaos. Without a well-designed plan, self-reliance turns into doubt and convictions into prejudice. Without a method to filter out irrelevancies, man gets lost in secondary roads that lead him away from his goals.

Lack of thoughtfulness leads to exaggerate problems and blow inconveniences out of proportion. Unclear expectations undermine reason. Confusion renders tasks heavier than they have to be. Contradictory values bring about unbridled emotions. Inconsistent criteria waste energy in endless discussions and destroys the ability to perform well.

In the kitchen, only detailed recipes give consistent results. Eating well is the overall objective, but actual cooking relies on specific ingredients, temperature, seasoning, and a formula that combines them. Failing to identify concrete elements of action makes impossible to implement plans and deprives man of confidence on his own abilities.

Imprecise plans and performance criteria blind our eyes. Today's random actions destroy yesterday's creations. Self-inflicted contradictions lead to failure, anger, and anxiety. A company whose employees render erratic, unpredictable services is doomed. Never trust individuals who are long on philosophical talk and short on implementation details.

Quality controls are useless if people don't know what they are doing. Quality requires clear objectives, purposeful thinking, and continuous action. If you want to be taken seriously, break down your twenty-year goals into monthly steps. The workable approach to happiness is a rational connection between our present actions and our life objectives.

Manufacturers follow a production formula to ensure that they are using the right materials. Check-lists permit managers to assess if a worker is sufficiently trained to do his job. A company's compensation plan aligns the interests of employees with the corporate goals.

Nobody can figure out all right answers all the time, but if you condense your strategy into a formula, mistakes will be self-correcting. Chaos leads to more chaos, but a recipe can be improved from experience. Breaking down long-term goals into detailed steps is of critical importance in business and private life.
