A certificate of 50 years old shows that you have worked for decades before. You must be very clear about this in your own work, that is, you know what you can do well, what you can do and what you can't do. You have worked for at least 25 years, and you naturally understand all these things. Then more is the adjustment of the family center of gravity. You are not so young now, and your work has basically reached its peak. In other words, the company will no longer promote a person over 50 years old, called the general manager or become such a high-level person. His time and energy can't keep up, and then you can take care of your family, educate your children, and even help your children solve some doubts in life, paving the way for the next generation. Your life is enough, and the rest can enjoy your old age.
