EngineerEngineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost.

PessimismPessimism is a negative mental attitude in which an undesirable outcome is anticipated from a given situation. Pessimists tend to focus on the negatives of life in general. A common question asked to test for pessimism is "Is the glass half empty or half full?"; in this situation, a pessimist is said to see the glass as half empty, or in extreme cases completely empty, while an optimist is said to see the glass as half full. Throughout history, the pessimistic disposition has had effects on all major areas of thinking.
