Engineer and Engineering Thinking ...
First of all, he is lazy.
But not apathetic. He just doesn't like walking the same path twice.
He doesn't do too much.
He optimizes known paths and thoroughly examines unknown ones before taking action. Sometimes his inaction is called procrastination. Sometimes - irrationality. But he will still achieve the result faster if he sets a goal. He looks for the meaning of the action before the action itself, otherwise why waste energy at all?
He will not act until he sees the complete and widest picture.
Sometimes the whole picture expands to the foundations of the universe. But there are engineers who immediately begin to experiment, expanding their understanding of the world with each new approach.
He doesn't like to waste resources - time, energy, money - in vain.
He follows the path of least resistance and knows how to achieve the goal with minimal effort, and at a new level of quality.
He doesn't want to talk to you, answer trivial questions and waste time on routine things.
And he values time and in every possible way tries to free him, inventing things that save him. His brain is very sensitive to complex tasks, insights and challenges. He is very resourceful in methods of avoiding and ignoring interference.
He values not only his time, but yours as well.
Therefore, he will first try to figure it out himself, and only then will he come with questions. It will be brief, speak to the point, give information in sequential blocks and in full, give data in a structured and accurate manner. He expects the same approach from others. If you have to provide information to an engineer, check and think seven times.
He is observant, but does not jump to conclusions.
He knows how to wait. He will criticize everything. But this is how he tests your readiness to implement your idea. Surely you missed something important.
There is deep logic in each of his actions.
Ask him how to choose an outfit or cook something delicious - you risk immersing yourself for several hours in the wonderful world of details, nuances and life hacks. This is his engineering thinking. Enjoy.
He is curious and looking for new approaches.
He wants to change the world. For your comfort and your l'arte di vivere - the art of living. It makes the complex accessible and easy to use.
