When you stop complaining about your work, that's when your strength begins. 
Jack Welch, renowned as the world's greatest CEO, worked at General Electric for a year in 1961. Due to his outstanding abilities and significant contributions to the company, he received a high annual performance rating. However, when he received a $1000 salary increase, he was disappointed to find out that others in the office received the same raise.

Welch believed that he should be rewarded more for his greater efforts. Unsatisfied, he confronted the company, but their explanation was that the salary increases were predetermined. This answer did not appease Welch, as he believed that the company should differentiate the salaries of its employees.

He spent days complaining, feeling dejected and even considering resigning. 

One day, his supervisor called him into the office and said, "Although you've only been at the company for a year, I admire your talent and enthusiasm. The road ahead is long. Complaining and not performing will only waste this great stage that the company offers.

Don't you want to stand in the center of this stage one day?" Finally, he realized that he needed to stop complaining and instead continue to showcase his abilities. Later, he became a project leader, leading teams to overcome challenges. He even volunteered to become the head of a processing plant, leading a materials revolution in the manufacturing industry. 

Just seven years later, at the age of 33, he became the youngest CEO in the history of General Electric. Reflecting on his career, Welch referred to this conversation with his supervisor as a pivotal moment that changed his destiny.
