You can have a great idea and execute it perfectly, all the while being convinced of its greatness and importance to humanity, but what's the point if others don't want to use it?

129 years ago, in 1885, Dr. Karl Benz invented the automobile. Presented a year later in Mannheim with patent number 37435, it brought Benz a flood of criticism. No one needed change. Today we know that no one KNEW they needed change.

Fortunately, Karl's wife, Bertha Benz, knew this. In 1888, secretly from her husband and accompanied by her two sons, she went to visit her mother. As is known, she is not the first woman to do something her own way, but thanks to this, she became the first person in the world to travel 106 kilometers without the help of a mechanic. This is a very long distance, considering that Mrs. Bertha's automobile, number 3, like all others at the time, did not have a fuel tank. Fuel had to be bought along the way, so Bertha simply bought it at a pharmacy in the town of Wiesloch she passed.
Yes, gas stations did not exist in 1888, because why would they. The pharmacy in Wiesloch, which still exists today, became the first gas station, and a monument to Bertha stands in front of it, and the entire Mannheim – Pforzheim route is a tourist trail commemorating the history of motoring.

Bertha proved to the disbelievers attacking her husband that motor vehicles are useful in everyday life. She herself, please, going to her mother, did not need a carriage or horses. She also proved to her husband that if he wanted to succeed, he had to show people what they would gain from this change. An idea is an idea, but practical Bertha knew her stuff.

Before Bertha and her sons reached their mother and grandmother, which she informed her husband about by telegram, they repaired what was breaking down in automobile no. 3 along the way: they unblocked the carburetor tube (with a brooch pin), changed the wire insulation at the ignition... Then Karl took all his wife's comments into account in subsequent models.

What do we get from all this? A few changes.

People believed in the sense and usefulness of using automobiles every day.
Gas stations were built.
Partly thanks to Bertha's jewelry, subsequent automobiles became less prone to breakdowns.
We are learning about marketing.

Marketing is about anticipating and creating change, and the ability to meet the needs of others.

P.S. If you know what Bertha wrote in the telegram to her husband, please tell me, I'm very curious.
